getdate — Get date/time information
$timestamp = time()
] )
Returns an associative array containing the date
information of the timestamp, or the current
local time if no timestamp is given.
Returns an associative array of information related to
the timestamp. Elements from the returned
associative array are as follows:
| Key | Description | Example returned values |
|---|---|---|
| "seconds" | Numeric representation of seconds | 0 to 59 |
| "minutes" | Numeric representation of minutes | 0 to 59 |
| "hours" | Numeric representation of hours | 0 to 23 |
| "mday" | Numeric representation of the day of the month | 1 to 31 |
| "wday" | Numeric representation of the day of the week | 0 (for Sunday) through 6 (for Saturday) |
| "mon" | Numeric representation of a month | 1 through 12 |
| "year" | A full numeric representation of a year, 4 digits | Examples: 1999 or 2003 |
| "yday" | Numeric representation of the day of the year | 0 through 365 |
| "weekday" | A full textual representation of the day of the week | Sunday through Saturday |
| "month" | A full textual representation of a month, such as January or March | January through December |
| 0 | Seconds since the Unix Epoch, similar to the values returned by time() and used by date(). | System Dependent, typically -2147483648 through 2147483647. |
Example #1 getdate() example
<?php
$today = getdate();
print_r($today);
?>
The above example will output something similar to:
Array
(
[seconds] => 40
[minutes] => 58
[hours] => 21
[mday] => 17
[wday] => 2
[mon] => 6
[year] => 2003
[yday] => 167
[weekday] => Tuesday
[month] => June
[0] => 1055901520
)
Andre's code will throw an error. for the following line
$d = $todayh[mday];
$m = $todayh[mon];
$y = $todayh[year];
"Notice : Undefined constant mday ,mon,year"
As is, it was looking for constants called mday, mon, year etc. When it doesn't find such a constant, PHP interprets it as a string.
like any other request it should be wrapped in quotes like this
$d = $todayh['mday'];
$m = $todayh['mon'];
$y = $todayh['year'];
In addition to canby23 at ms19 post:
It's a very bad idea to consider day having 24 hours (86400 secs), because some days have 23, some - 25 hours due to daylight saving changes. Using of mkdate() and strtotime() is always preferred. strtotime() also has a very nice behaviour of datetime manipulations:
<?php
echo strtotime ("+1 day"), "\n";
echo strtotime ("+1 week"), "\n";
echo strtotime ("+1 week 2 days 4 hours 2 seconds"), "\n";
echo strtotime ("next Thursday"), "\n";
echo strtotime ("last Monday"), "\n";
?>
I thought best to show a posseble way to go about bypassing the end month issue where the first day in a new month will have the monday of the week that it falls in - in the old month. Use the numbering of days as the constant and work you way from there.
Example:
<?php
//-----------------------------
$now = time();
$num = date("w");
if ($num == 0)
{ $sub = 6; }
else { $sub = ($num-1); }
$WeekMon = mktime(0, 0, 0, date("m", $now) , date("d", $now)-$sub, date("Y", $now)); //monday week begin calculation
$todayh = getdate($WeekMon); //monday week begin reconvert
$d = $todayh[mday];
$m = $todayh[mon];
$y = $todayh[year];
echo "$d-$m-$y"; //getdate converted day
?>
Allot less code makes everyone happy..
It's worth noting that this is local time, not UTC/GMT - gmgetdate doesn't exist :(.
The most logical way to handle date arithmetic without hitting DST problems is to work in UTC...
<?php
function add_days($my_date,$numdays) {
$date_t = strtotime($my_date.' UTC');
return gmdate('Y-m-d',$date_t + ($numdays*86400));
}
?>
[it's even faster if you use gmmktime instead of strtotime]
Here is another gmgetdate that is a little faster/suscint (no loops).
<?php
function gmgetdate2($ts = null){
$k = array('seconds','minutes','hours','mday',
'wday','mon','year','yday','weekday','month',0);
return(array_combine($k,split(":",
gmdate('s:i:G:j:w:n:Y:z:l:F:U',is_null($ts)?time():$ts))));
}
?>
It also returns the values in the same order as getdate.
