number_format — Format a number with grouped thousands
$number
[, int $decimals = 0
] )$number
, int $decimals = 0
, string $dec_point = "."
, string $thousands_sep = ","
)This function accepts either one, two, or four parameters (not three):
If only one parameter is given,
number will be formatted without decimals,
but with a comma (",") between every group of thousands.
If two parameters are given, number will
be formatted with decimals decimals with a
dot (".") in front, and a comma (",") between every group of
thousands.
If all four parameters are given, number
will be formatted with decimals decimals,
dec_point instead of a dot (".") before
the decimals and thousands_sep instead of
a comma (",") between every group of thousands.
numberThe number being formatted.
decimalsSets the number of decimal points.
dec_pointSets the separator for the decimal point.
thousands_sepSets the thousands separator.
A formatted version of number.
| Version | Description |
|---|---|
| 5.4.0 |
This function now supports multiple bytes in
dec_point and
thousands_sep. Only the first byte of each
separator was used in older versions.

Example #1 number_format() Example
For instance, French notation usually use two decimals, comma (',') as decimal separator, and space (' ') as thousand separator. This is achieved with this line :
<?php
$number = 1234.56;
// english notation (default)
$english_format_number = number_format($number);
// 1,235
// French notation
$nombre_format_francais = number_format($number, 2, ',', ' ');
// 1 234,56
$number = 1234.5678;
// english notation without thousands separator
$english_format_number = number_format($number, 2, '.', '');
// 1234.57
?>
It's not explicitly documented; number_format also rounds:
<?php
$numbers = array(0.001, 0.002, 0.003, 0.004, 0.005, 0.006, 0.007, 0.008, 0.009);
foreach ($numbers as $number)
print $number."->".number_format($number, 2, '.', ',')."<br>";
?>
0.001->0.00
0.002->0.00
0.003->0.00
0.004->0.00
0.005->0.01
0.006->0.01
0.007->0.01
0.008->0.01
0.009->0.01
Outputs a human readable number.
<?php
# Output easy-to-read numbers
# by james at bandit.co.nz
function bd_nice_number($n) {
// first strip any formatting;
$n = (0+str_replace(",","",$n));
// is this a number?
if(!is_numeric($n)) return false;
// now filter it;
if($n>1000000000000) return round(($n/1000000000000),1).' trillion';
else if($n>1000000000) return round(($n/1000000000),1).' billion';
else if($n>1000000) return round(($n/1000000),1).' million';
else if($n>1000) return round(($n/1000),1).' thousand';
return number_format($n);
}
?>
Outputs:
247,704,360 -> 247.7 million
866,965,260,000 -> 867 billion
I ran across an issue where I wanted to keep the entered precision of a real value, without arbitrarily rounding off what the user had submitted.
I figured it out with a quick explode on the number before formatting. I could then format either side of the decimal.
<?php
function number_format_unlimited_precision($number,$decimal = '.')
{
$broken_number = explode($decimal,$number);
return number_format($broken_number[0]).$decimal.$broken_number[1];
}
?>
// Here is a function that produces the same output as number_format() but also works with numbers bigger than 2^53.
function a_number_format($number_in_iso_format, $no_of_decimals=3, $decimals_separator='.', $thousands_separator='', $digits_grouping=3){
// Check input variables
if (!is_numeric($number_in_iso_format)){
error_log("Warning! Wrong parameter type supplied in my_number_format() function. Parameter \$number_in_iso_format is not a number.");
return false;
}
if (!is_numeric($no_of_decimals)){
error_log("Warning! Wrong parameter type supplied in my_number_format() function. Parameter \$no_of_decimals is not a number.");
return false;
}
if (!is_numeric($digits_grouping)){
error_log("Warning! Wrong parameter type supplied in my_number_format() function. Parameter \$digits_grouping is not a number.");
return false;
}
// Prepare variables
$no_of_decimals = $no_of_decimals * 1;
// Explode the string received after DOT sign (this is the ISO separator of decimals)
$aux = explode(".", $number_in_iso_format);
// Extract decimal and integer parts
$integer_part = $aux[0];
$decimal_part = isset($aux[1]) ? $aux[1] : '';
// Adjust decimal part (increase it, or minimize it)
if ($no_of_decimals > 0){
// Check actual size of decimal_part
// If its length is smaller than number of decimals, add trailing zeros, otherwise round it
if (strlen($decimal_part) < $no_of_decimals){
$decimal_part = str_pad($decimal_part, $no_of_decimals, "0");
} else {
$decimal_part = substr($decimal_part, 0, $no_of_decimals);
}
} else {
// Completely eliminate the decimals, if there $no_of_decimals is a negative number
$decimals_separator = '';
$decimal_part = '';
}
// Format the integer part (digits grouping)
if ($digits_grouping > 0){
$aux = strrev($integer_part);
$integer_part = '';
for ($i=strlen($aux)-1; $i >= 0 ; $i--){
if ( $i % $digits_grouping == 0 && $i != 0){
$integer_part .= "{$aux[$i]}{$thousands_separator}";
} else {
$integer_part .= $aux[$i];
}
}
}
$processed_number = "{$integer_part}{$decimals_separator}{$decimal_part}";
return $processed_number;
}
$original_number= 9223372036854775805;
echo a_number_format($original_number, 4, '.',"'",3);
// Outputs: 9'223'372'036'854'775'805.1230
For Zero fill - just use the sprintf() function
$pr_id = 1;
$pr_id = sprintf("%03d", $pr_id);
echo $pr_id;
//outputs 001
-----------------
$pr_id = 10;
$pr_id = sprintf("%03d", $pr_id);
echo $pr_id;
//outputs 010
-----------------
You can change %03d to %04d, etc.
Just an observation:
The number_format rounds the value of the variable.
$val1 = 1.233;
$val2 = 1.235;
$val3 = 1.237;
echo number_format($val1,2,",","."); // returns: 1,23
echo number_format($val2,2,",","."); // returns: 1,24
echo number_format($val3,2,",","."); // returns: 1,24
In my function my_number_format() [shown below] there was a bug.
If a negative number which is smaller than 1 was entered (-0,...), then the result was wrongly positive because +0 is equal to -0 (the content of $tmp[0] which was interpretet as numeric value).
Here is the corrected version:
<?php
function my_number_format($number, $dec_point, $thousands_sep)
{
$was_neg = $number < 0; // Because +0 == -0
$number = abs($number);
$tmp = explode('.', $number);
$out = number_format($tmp[0], 0, $dec_point, $thousands_sep);
if (isset($tmp[1])) $out .= $dec_point.$tmp[1];
if ($was_neg) $out = "-$out";
return $out;
}
?>
Thanks to Federico Cassinelli for the bug report.
[EDIT BY danbrown AT php DOT net: The original note follows.]
Let's say we got the number $inp = 1234.56
By using
<?php
return number_format($inp, 2, ',', '.');
?>
you can get the German format 1.234,56. (Comma as decimal separator and point as thousand separator)
But I have a problem with that: I want to add commas as thousand separators and change the decimal-separator (this could also be done with str_replace), but I do not want to change the amount of fractional digits!
But since the 2nd argument of number_format is necessary to enter the 3rd and 4th argument, this cannot be done with number_format. You have to change the fractional digits with this function.
But I want that 1234.56 changes into 1.234,56 and 1234.567890123456 changes into 1.234,567890123456
So, I created following function, that doesn't change the amount of fractional digits:
<?php
function my_number_format($number, $dec_point, $thousands_sep)
{
$tmp = explode('.', $number);
$out = number_format($tmp[0], 0, $dec_point, $thousands_sep);
if (isset($tmp[1])) $out .= $dec_point.$tmp[1];
return $out;
}
?>
I'm not sure if this is the right place anyway, but "ben at last dot fm"'s ordinal function can be simplified further by removing the redundant "floor" (the result of floor is still a float, it's the "%" that's converting to int) and outer switch.
Note that this version also returns the number with the suffix on the end, not just the suffix.
<?php
function ordinal($num)
{
// Special case "teenth"
if ( ($num / 10) % 10 != 1 )
{
// Handle 1st, 2nd, 3rd
switch( $num % 10 )
{
case 1: return $num . 'st';
case 2: return $num . 'nd';
case 3: return $num . 'rd';
}
}
// Everything else is "nth"
return $num . 'th';
}
?>
If you use space as a separator, it will break on that space in HTML tables...
Furthermore, number_format doesn't like ' ' as a fourth parameter. I wrote the following function to display the numbers in an HTML table.
function numberfix($number)
{
$number = number_format($number,0,","," ");
return str_replace(" ", " ", $number);
}
For use in:
<table><tr><td><?php echo $number; ?></td></tr></table>
I was looking for a SIMPLE way to format currency and account for negative values while not losing the calculation properties of my number. Here's my function - it's not rocket science, but maybe can help someone along the way.
<?php
function wims_currency($number) {
if ($number < 0) {
$print_number = "($ " . str_replace('-', '', number_format ($number, 2, ".", ",")) . ")";
} else {
$print_number = "$ " . number_format ($number, 2, ".", ",") ;
}
return $print_number;
}
?>
Sample use:
<?php
$pur_po_total = ($pur_po_total + $pur_item_total);
$print_pur_po_total = wims_currency($pur_po_total);
?>
Returns (for example) $ 44,561.00 or, if a negative ($ 407,250.00)
This way, I use my 1st variable for calculations and my 2nd variable for output. I'm sure there are better ways to do it, but this got me back on track.
To prevent the rounding that occurs when next digit after last significant decimal is 5 (mentioned by several people below):
<?php
function fnumber_format($number, $decimals='', $sep1='', $sep2='') {
if (($number * pow(10 , $decimals + 1) % 10 ) == 5) //if next not significant digit is 5
$number -= pow(10 , -($decimals+1));
return number_format($number, $decimals, $sep1, $sep2);
}
$t=7.15;
echo $t . " | " . number_format($t, 1, '.', ',') . " | " . fnumber_format($t, 1, '.', ',') . "\n\n";
//result is: 7.15 | 7.2 | 7.1
$t=7.3215;
echo $t . " | " . number_format($t, 3, '.', ',') . " | " . fnumber_format($t, 3, '.', ',') . "\n\n";
//result is: 7.3215 | 7.322 | 7.321
} ?>
have fun!
To separate big numbers like the spanish language you can do this:
Tis example is based on facebook followers:
number_format ($infoF , 0 , ' , ' , '.');
it will output:
//1.187.037
instead of comas.
formatting numbers may be more easy if u use number_format function.
I also wrote this :
function something($number)
{
$locale = localeconv();
return number_format($number,
$locale['frac_digits'],
$locale['decimal_point'],
$locale['thousands_sep']);
}
hope this helps =)

$multiplier — typically used to adjust prices up or down.
*/
if ($format) {
$format += ['numOfDecimals' => 0, 'decimalSeparator' => '.', 'thousandSeparator' => '']; # Default format
# Find decimal separator
# The decimal separator is the one that is the last and does not occur more than once
if ($letters = str_replace(' ', '', $number)) { # Replace spaces
if ($letters = preg_replace('/^-/', '', $letters)) { # Remove minus
if ($letters = preg_replace('/[0-9]/', '', $letters)) { # Get all non digits

I came into a need to show two decimal places, but the desire to drop the decimal portion off if it is zero. This function is a direct replacement for number_format:
<?PHP
function number_format_clean($number,$precision=0,$dec_point='.',$thousands_sep=',')
{
RETURN trim(number_format($number,$precision,$dec_point,$thousands_sep),'0'.$dec_point);
}
?>
Example:
<?PHP
echo number_format_clean(25.00,2);
echo number_format_clean(25.52,2);
echo number_format_clean(50.10,2);
echo number_format_clean(05.50,2);
?>
Outputs:
25
25.52
50.1
5.5
Good for weight conversions (1 oz vs. 1.00 oz). Feels less "automated."
The above will trim all insignificant zeros from both ends of the string, though I'm not sure I've ever seen leading zeros returned.

Here a function to filter exponential notation like 6e-06. Turn it to 0,000006 for comfortable reading. Supporting various number of decimals!
<?php
function easy_number_format($number, $dec_point, $thousands_sep)
{
$number = rtrim(sprintf('%f', $number), "0");
if (fmod($nummer, 1) != 0) {
$array_int_dec = explode('.', $number);
} else {
$array_int_dec= array(strlen($nummer), 0);

return number_format($number, $decimals, $dec_point, $thousands_sep);
}
?>
The maximum accuracy depends on sprintf('%f', $number). In this case 6 decimals. Expand it to 10 with '%.10f'.
There has been some suggestions around on how to keep trailing zeros. Best way is to use the example for currency provided by the php-crew in the sprintf function help section.
That is:
<?php
$money1 = 68.75;
$money2 = 54.35;
$money = $money1 + $money2;
// echo $money will output "123.1";
$formatted = sprintf("%01.2f", $money); // << this does the trick!
// echo $formatted will output "123.10"
?>

Some programmers may have scripts that use the number_format function twice on a variable. However, if a number is 4 or more digits, using the function twice with only the decimals parameter will lose part of the value that follows the thousands separator.
<?php
$var = number_format(2234,2);
$var = number_format($var,2);
echo $var;
# Expected Output: 2,234.00
# Actual Output: 2.00
?>
To fix, remove the thousands separator by setting the decimal point and thousands separator parameters like so:
<?php
$var = number_format(2234,2,'.','');
$var = number_format($var,2,'.','');
echo $var;
# Expected Output: 2234.00
# Actual Output: 2234.00
?>
If it's 3 digits or less, then it works normally with only the decimals parameter since there is no thousands separator.
<?php
$var = number_format(123,2);
$var = number_format($var,2);
echo $var;
# Expected Output: 123.00
# Actual Output: 123.00
?>

switch( $i % 10 ) {
case 1: return 'st';
case 2: return 'nd';

And remember to always contribute custom functions if they might be useful to the rest of us or future versions of the php language.
Exemplo: Example:
<?php
$number = 1234567.896;
echo '1: '.number_format($number, 2, ',', '').'<br>';
echo '2: '.number_format($number, 2, '.', '').'<br>';
echo '3: '.number_format($number, 2, ',', '.').'<br>';
echo '4: '.number_format($number, 2, '.', ',').'<br>';
echo '5: '.number_format($number, 2, ',', ' ').'<br>';
echo '6: '.number_format($number, 2, ',', "'").'<br>';
echo '7: '.number_format($number, 2, '', '').'<br>';
?>
Resultado: Result:

Using the number_format I'm having some unexpected results. 30% of 14.95 (14.95 * .3) = 4.485. Now 4.485 rounded to two decimal places should give me 4.49.
Example:
<?php
echo number_format(14.95 * .3, 2, '.', '') . "\n";
echo number_format(4.485, 2, '.', '') . "\n";
?>
Unexpected Results:
4.48
4.49
I have to verify price data from several formats, eg:
- 12.345,67 (German)
- 12,345.67 (English)
- 12 345,67 (French)
- 12'345,67 (Swiss)
Here is a quick function which helps me out of all this format mess, but please not the I only check for:
- positive values
- max 2 digits on the right side (.12)
function mk_price_to_float($price){
$price = trim($price);
if(preg_match("~^([0-9]+|(?:(?:[0-9]{1,3}([.,' ]))+[0-9]{3})+)(([.,])[0-9]{1,2})?$~", $price, $r)){
if(!empty($r['2'])){
$pre = preg_replace("~[".$r['2']."]~", "", $r['1']);
}else{
$pre = $r['1'];
}
if(!empty($r['4'])){

simpler function to convert a number in bytes, kilobytes....

you may also add others units over PeraBytes when the hard disks will reach 1024 PB :)
This is a simple and useful function to convert a byte number in a KB or MB:

If you want to display a number ending with ,- (like 200,-) when there are no decimal characters and display the decimals when there are decimal characters i use:
function DisplayDouble($value)
{
list($whole, $decimals) = split ('[.,]', $value, 2);
if (intval($decimals) > 0)
return number_format($value,2,".",",");
else
return number_format($value,0,".",",") .",-";
}
See also the documentation for localeconv, which will provide values for decimal point and thousands separator from the C standard library.
Of course localeconv features many more locale information, like indicating to put the negative sign behind the value for some locale settings which can't be used to customize present number_format.
To convert numbers to thier textual representations, you can use an adapted version of the Number::Spell Perl module. The PHP conversion can be found here: http://pear.php.net/package/Numbers_Words
if you converted a number to a German format with number_format() and want to save it in mySQL, you first have to change the number format back to an English format.
For example
10.453,21 >>>> 10453.21
Here is an example how to do this:
$field_array=explode(".", $field_inhalt);
$field_inhalt=$field_array[0].$field_array[1];
$foeld_array=explode(",", $field_inhalt);
$field_inhalt=$field_array[0].".".$feld_array[1];
$field_inhalt=sprintf($field_inhalt, 2);
$field_inhalt is the variable of the actual number you want to change to the english format.
About the function of j-a-n at gmx dot de: it's useful, but the argument of the function is $number while the logic of the function requires it to be $in.
The modification to number_format below does what I actually want it to do, with currency, for example. I want it to show $1.40 and not $1.4 or $1.400 - except in the rare case where I have $1.435 for something, in which case I *don't* want it to round. The ugliness below serves my purpose.
function nof($number,$decimals) {
if (number_format($number,$decimals,'.',',') != $number) {
return $number;
} else {
return number_format($number,$decimals,'.',',');
}
}
You could use the following regular expression to divide
a number into parts:
$1-number without fractal part
$2-fractal part
$3-first 2 digits of the fractal part
$4-rest of the fractal part
the regex removes any leading and trailing symbols and leading zeros. It doesnt validate the number, so 12 41 is considered to be correct input!
english notation:
/^.*?[0]*([\d\s]+)(([\.][\d]{0,2})([\d]*))?.*?$/
french notation:
/^.*?[0]*([\d\s]+)(([\,][\d]{0,2})([\d]*))?.*?$/
<?php
// truncate the fractal part up to 2 digits of an "english number":
$number = '01,234.50789';
$trunc = preg_replace(
'/^.*?[0]*([\d\,]+)(([\.][\d]{0,2})([\d]*))?.*?$/',
'$1$3',
$number
);
echo $trunc;
?>
Outputs:
1,234.50
$number='e00012 41.100001e-4fasfd';
would output:
12 41.10
A bug was issued that -0,00 is invalid output from number_format(), but the bug was rejected since the number "-0.0000000000000000001E-999 is about -0". And the developer felt this was correct output.
Please beware of negative numbers close to zero, as they might produce this unusable (and in my opinion incorrect/off-description) output.
A more reliable and concise way of doing what S. Rahmel was trying to do below is as follows:
<?php
$field_inhalt = str_replace(array(".", ","), array("", "."), $field_inhalt);
?>
The str_replace() call will first replace all dots with blanks, and then replace all commas with dots. That way, it doesn't break down when you try a number over one million (i.e. 1.010.453,21).
Drew
enjoy the PHP!
<?php
function FormatPrice($price) {
$price = preg_replace("/[^0-9\.]/", "", str_replace(',','.',$price));
if (substr($price,-3,1)=='.') {
$sents = '.'.substr($price,-2);
$price = substr($price,0,strlen($price)-3);
} elseif (substr($price,-2,1)=='.') {
$sents = '.'.substr($price,-1);
$price = substr($price,0,strlen($price)-2);
} else {
$sents = '.00';
}
$price = preg_replace("/[^0-9]/", "", $price);
return number_format($price.$sents,2,'.','');
}
?>
number_format is pretty fast. It's much slower than calculation though:
<?php
$start = microtime(true);
echo "<pre>";
for ($i=0;$i<100000;$i++)
{
echo number_format(microtime(true)-$start,25)."\n";
}
echo "<hr />Parsetime: ".(microtime(true)-$start);
?>
This takes 1.03 seconds all the time. Without the -$start in the number_format cmd, it takes exactly as long (I ran it about 20 times).
The simple calculation inside number_format takes relatively no time. Defining the number before entering it into number_format also gives no change:
{
$num = microtime(true)-$start;
echo number_format($num,25)."\n";
}
Which concludes it takes about .01 sec to do a thousand number_format.
If you'd do the same routine without the number_format, it'd take .75 seconds -> number_format very fast!
I'd like to comment to the old notes of "stm555" and "woodynadobhar".
They wrote about "number_format_unlimited_precision()".
I guess many of us need that kind of function, which is the almost same function as number_format but don't round a number.
Does Anyone know any new solution in a recent PHP version?
...
If no, how about the following function? (I fixed somethings like bugs of the function in the old comment.)
<?php
function number_format_unchanged_precision($number, $dec_point='.', $thousands_sep=','){
if($dec_point==$thousands_sep){
trigger_error('2 parameters for ' . __METHOD__ . '() have the same value, that is "' . $dec_point . '" for $dec_point and $thousands_sep', E_USER_WARNING);
// It corresponds "PHP Warning: Wrong parameter count for number_format()", which occurs when you use $dec_point without $thousands_sep to number_format().
}
if(preg_match('{\.\d+}', $number, $matches)===1){
$decimals = strlen($matches[0]) - 1;
}else{
$decimals = 0;
}
return number_format($number, $decimals, $dec_point, $thousands_sep);
}
var_dump(number_format_unchanged_precision(1234.5678, ',', '.'));
var_dump(number_format_unchanged_precision(1234.5678, ','));
var_dump(number_format_unchanged_precision(12345678));
var_dump(number_format_unchanged_precision(-0.5678, ',', '.')); // It occurred a bug with the function in the old comment.
?>
output is:
string(10) "1.234,5678"
PHP Warning: 2 parameters for number_format_unchanged_precision() have the same value, that is "," for $dec_point and $thousands_sep in...
string(10) "1,234,5678"
string(10) "12,345,678"
string(7) "-0,5678"
function formats numbers of datetime type,
<?php
$_GET["zaman"]="1983-8-28 5:5:5";
function _parseDatetimeToList($datetimeStr) { //datetime format: Y-m-d H-i-s
$datetimeArray=explode(" ", $datetimeStr);
$dateArray=explode("-",$datetimeArray[0]);
$year=str_pad($dateArray[0], 2, "0", STR_PAD_LEFT);
$month=str_pad($dateArray[1], 2, "0", STR_PAD_LEFT);
$day=str_pad($dateArray[2], 2, "0", STR_PAD_LEFT);
$timeArray=explode(":",$datetimeArray[1]);
$hour=str_pad($timeArray[0], 2, "0", STR_PAD_LEFT);
$minute=str_pad($timeArray[1], 2, "0", STR_PAD_LEFT);
$second=str_pad($timeArray[2], 2, "0", STR_PAD_LEFT);
return array($year, $month, $day, $hour, $minute, $second);
}
list($year, $month, $day, $hour, $minute, $second) = _parseDatetimeToList($_GET["zaman"]); // 1983-1-28 5:5:5
?>
Maybe it is documented, but I just missed it. However, a comment is always useful.
An array will always be converted into 1, so, if you have:
<?php
$my_array = array(55);
echo number_format($my_array,0,',','.');
// 1
var_dump(number_format($my_array,2,',','.'));
// string(4) "1,00"
?>
Since it took me a while to figure it out, I hope this will save somebody's time.
Greetings !!
When apply number_format on number with separator on thousands, result is wrong. This function accept number of any format
<?php
function format_price($number,$decPlaces,$decSep,$thouSep){
//$number - number for format
//$decPlaces - number of decimal places
//$decSep - separator for decimals
//$thouSep - separator for thousands
//first remove all white spaces
$number=preg_replace('/\s+/', '',$number);
//split string into array
$numberArr = str_split($number);
//reverse array and not preserve key, keys will help to find decimal place
$numberArrRev=array_reverse($numberArr);
//find first occurrence of non number character, that will be a decimal place
//store $key into variable $decPointIsHere
foreach ($numberArrRev as $key => $value) {
if(!is_numeric($value)){
if($decPointIsHere==""){
$decPointIsHere=$key;
}
}
}
//decimal comma or whatever it is replace with dot
//$decPointIsHere is the key of the element that will contain decimal separator dot
if($decPointIsHere!=""){
$numberArrRev[$decPointIsHere]=".";
}
//again check through array for non numerical characters but skipping allready processed keys
//if is not number remove from array
foreach ($numberArrRev as $key => $value) {
if(!is_numeric($value) && $key>$decPointIsHere){
unset($numberArrRev[$key]);
}
}
//reverse back, at the start reversed array $numberArrRev to $numberArr
$numberArr=array_reverse($numberArrRev);
//create string from array
$numberClean=implode("",$numberArr);
// apply php number_format function
return number_format($numberClean,$decPlaces,$decSep,$thouSep);
}
echo format_price("1 225 552, 55",2,',',' ')."<br>";
echo format_price("1.225.552, 55",2,',',' ')."<br>";
echo format_price("1'225'552. 55",2,',',' ')."<br>";
echo format_price("1225552.55",2,',',' ')."<br>";

all results are: 1 225 552,55

A simple funtion to format american dollars.
<?php
function formatMoney($money) {
if($money<1) {
$money='¢'.$money*100;
}
else {
$dollars=intval($money);
$cents=$money-$dollars;
$cents=$cents*100;
$money='$'.$dollars.' and ¢'.$cents;
}
return $money;
}
echo formatmoney('52.342');
?>
This will output: " $52 and ¢34.2 ".
What do you do if some of your numbers have decimal places, and some don't? You can switch between functions, but if you're building it in a loop, that's not a good solution. Instead, we have the same as below, with a slight change:
function number_format_unlimited_precision($number,$decimal = '.'){
$broken_number = explode($decimal,$number);
if($broken_number[1]==0){
return number_format($broken_number[0]);
}else{
return number_format($broken_number[0]).$decimal.$broken_number[1];
};
};
Sometimes, I'm sure, you guys are looking for a way to do the exact opposite of this function: convert a comma-filled number back to normal decimal.
Here's a quick code that popped into my head today:
<?php
$mynumstr = "100,000,000.75";
$mynum = doubleval(str_replace(",","",$mynumstr));
?>
This is especially useful when validating user input. Some people like to include comma's with their numbers.
Some also like to include the dollar-sign when entering prices. Here's a modification:
<?php
$mynumstr = '$100,000,000.25';
$arr1 = array(',','$');
$arr2 = array('','');
$mynum = doubleval(str_replace($arr1,$arr2,$mynumstr));
//The arrays had to be defined in a
// variable to shorten statement.
?>
Okay, that takes care of it, I use the PHP4 array compatibility update to remove several characters.
Don't forget to either use single-quotes or escape the dollar-sign!

As many people state the number_format function will round. Now if you're like me and you don't want stuff to round (and the functions below do not work for you) you can try a little regex:
<?php
function convert_size_human($size){
$unit=array('','KB','MB','GB','TB','PB');
$byte_size = $size/pow(1024,($i=floor(log($size,1024))));
if(is_really_int($byte_size)){
return $byte_size.' '.$unit[$i];
}else{
preg_match('/^[0-9]+\.[0-9]{2}/', $byte_size, $matches);
return $matches[0].' '.$unit[$i];
}
}
?>
The regex used when the number is not an int ensures that 3.99887 GB comes out as 3.99 GB instead of 4GB as it does from number_format or the functions below.
Remember that number_format returns a string, so you shouldn't run a number_format on a variable that's already a product of number_format (it will only take the first token of the string)...
eg. echo number_format("123,456.00", 2);
produces: 123.00
if you want as a separator and use windows charset this piece of code may help:
<?php
$number=number_format($number,2,'.',chr(0xA0));
?>
You could add padding zeros like this:
<?
$number="129";
$number=sprintf("%08d",$number);
?>
number_format($number,$precision,".","") should be used when setting the value of form elements because if you read the number into a double upon submission, it will only store digits before the comma.
<p>
ie. <input type="text" value="<?php echo(number_format(2.5343,2,".","")">
Since number_format returns a string, you must perform all mathmatical functions on the number before applying number_format:
<?

The function rlerne posted does not work well in many cases:
<?php
function number_format_clean($number, $precision = 0, $dec_point = '.', $thousands_sep = ',') {
return trim(number_format($number, $precision, $dec_point ,$thousands_sep), '0' . $dec_point);
}
?>
Fail examples:
<?php
number_format_clean(0.1, 2); // returns "1"
number_format_clean(10.000001, 2); // returns "1"
?>
This one is correct:
<?php
function number_format_clean($number, $precision = 0, $dec_point = '.', $thousands_sep = ',') {
return rtrim(rtrim(number_format($number, $precision, $dec_point ,$thousands_sep), '0'), $dec_point);
}
?>
This function formats an decimal number to a String.
But it does'n use an fixed count of decimals but calculates the needed count of decimals.
<?
function formatNumber( $number, $decimals=2, $dec_point=".", $thousands_sep=",") {
$nachkomma = abs($in - floor($in));
$strnachkomma = number_format($nachkomma , $decimals, ".", "");
for ($i = 1; $i <= $decimals; $i++) {
if (substr($strnachkomma, ($i * -1), 1) != "0") {
break;
}
}
return number_format($in, ($decimals - $i +1), $dec_point, $thousands_sep);
}
?>
Example:
formatNumber( 100.00 );
--> 100
formatNumber( 100.50 );
--> 100.5
formatNumber( 100.1234 );
--> 100.12
formatNumber( 100.12, 4 );
--> 100.12
formatNumber( 100.12345, 4 );
--> 100.1234
People here in India are more used to counting money in Lakhs & Crores .. so here is the code for formatting the commas with thousands for the first time and then with hundred multiples from there after.
Ex: 1234567 -> 12,34,567
<?php
function makecomma($input)
{
// This function is written by some anonymous person - I got it from Google
if(strlen($input)<=2)
{ return $input; }
$length=substr($input,0,strlen($input)-2);
$formatted_input = makecomma($length).",".substr($input,-2);
return $formatted_input;
}
function formatInIndianStyle($num){
// This is my function
$pos = strpos((string)$num, ".");
if ($pos === false) { $decimalpart="00";}
else { $decimalpart= substr($num, $pos+1, 2); $num = substr($num,0,$pos); }
if(strlen($num)>3 & strlen($num) <= 12){
$last3digits = substr($num, -3 );
$numexceptlastdigits = substr($num, 0, -3 );
$formatted = makecomma($numexceptlastdigits);
$stringtoreturn = $formatted.",".$last3digits.".".$decimalpart ;
}elseif(strlen($num)<=3){
$stringtoreturn = $num.".".$decimalpart ;
}elseif(strlen($num)>12){
$stringtoreturn = number_format($num, 2);
}
if(substr($stringtoreturn,0,2)=="-,"){$stringtoreturn = "-".substr($stringtoreturn,2 );}
return $stringtoreturn;
}
$num = 1234567;
echo formatInIndianStyle($num);
?>
The following function converts a string into Float or Integer while taking the given or locale number format into account.
<?php
function strtonumber( $str, $dec_point=null, $thousands_sep=null )
{
if( is_null($dec_point) || is_null($thousands_sep) ) {
$locale = localeconv();
if( is_null($dec_point) ) {
$dec_point = $locale['decimal_point'];
}
if( is_null($thousands_sep) ) {
$thousands_sep = $locale['thousands_sep'];
}
}
$number = (float) str_replace($dec_point, '.', str_replace($thousands_sep, '', $str));
if( $number == (int) $number ) {
return (int) $number;
} else {
return $number;
}
}
?>
If you want to use nbsp as decimal/thousand delimiter with UTF-8 you have to replace the whitespace after using number_format:
<?php
$number = number_format(1000, 0, ".", " "); // normal space
echo str_replace(" ", utf8_encode("\xA0"), $number);
// or
echo str_replace(" ", html_entity_decode(" ", ENT_COMPAT, "UTF-8"), $number);
?>
this also works as well
$number = "29346.99"; //value
echo "$" .number_format($number, 2, '.', ',');
produces $29,346.99
One-liner to add filesizes and print a human readable result:
seq 1 500 | php -r '$t=0;while(1){$a=rtrim(fgets(STDIN));if(feof(STDIN))break;$t+=$a+0;} $p=floor(log($t, 1024)); printf("%.0f%s\n", $t/pow(1024,$p),substr("BKMGT",$p,1));'

To address the problems number_format has when dealing with big numbers I've created my own Number_Format method, it acts the same way as number_format and takes the same arguments but deals with numbers as strings solving the problems above referred.
(The other methods are available at http://www.alixaxel.com/wordpress/2007/05/19/php-math-library/)
function Number_Format($number, $decimal_precision = 0, $decimals_separator = '.', $thousands_separator = ',')
{
if ($this->Is_Negative($number))
{
$negative = true;
$number = str_replace('-', '', $number);
}
$number = explode('.', str_replace(' ', '', $number));
$number[0] = str_split(strrev($number[0]), 3);
$total_segments = count($number[0]);
for ($i = 0; $i < $total_segments; $i++)
{
$number[0][$i] = strrev($number[0][$i]);
}
$number[0] = implode($thousands_separator, array_reverse($number[0]));
if ($negative === true)
{
$number[0] = '-' . $number[0];
}
if (!empty($number[1]))
{
$number[1] = $this->Round($number[1], $decimal_precision);
}
$number = implode($decimals_separator, $number);
return $number;
}
I hope this is useful for someone!
