mysql_fetch_row — Get a result row as an enumerated array
This extension was deprecated in PHP 5.5.0, and it was removed in PHP 7.0.0. Instead, the MySQLi or PDO_MySQL extension should be used. See also MySQL: choosing an API guide and related FAQ for more information. Alternatives to this function include:
$result
)Returns a numerical array that corresponds to the fetched row and moves the internal data pointer ahead.
resultThe result resource that is being evaluated. This result comes from a call to mysql_query().
Returns an numerical array of strings that corresponds to the fetched row, or
FALSE if there are no more rows.
mysql_fetch_row() fetches one row of data from the result associated with the specified result identifier. The row is returned as an array. Each result column is stored in an array offset, starting at offset 0.
Example #1 Fetching one row with mysql_fetch_row()
<?php
$result = mysql_query("SELECT id,email FROM people WHERE id = '42'");
if (!$result) {
echo 'Could not run query: ' . mysql_error();
exit;
}
$row = mysql_fetch_row($result);
echo $row[0]; // 42
echo $row[1]; // the email value
?>
Note: This function sets NULL fields to the PHP
NULLvalue.
to print an array, simply use print_r(array name)
like this:
$myrow = mysql_fetch_row($result);
echo "<pre>";
print_r($myrow);
echo "</pre>";
this will output the array in a readable form, with the index, too. Don't forget the 'pre' tags or the output will be on a single line.
Maybe worth pointing out that all the fields returned by this (and other?) calls are returned with type string. This had me puzzled for quite some time.
sry :) note now fixed:
<?php
$esi=mysql_list_tables($db);$ris=mysql_fetch_row($esi);
//example: $db has >= 1 tabs
echo var_dump($ris);
//echoes only array(1). solution:
while($ris=mysql_fetch_row($esi)) echo $ris[0];
/*debug:
$ris=array("1st_tab"); ... $ris=array("n_tab");$ris=false;*/
while ($ris[]=mysql_fetch_row($esi));
//debug:$ris=array(array("1st_tab"), ... array("n_tab"));
echo $ris[n][0];//echo:"n_tab"
echo $ris[0][n];//echo:array | null
?>
hope it helps
The following function to read all data out of a mysql-resultset, is may be faster than Rafaels solution:
<?
function mysql_fetch_all($result) {
while($row=mysql_fetch_array($result)) {
$return[] = $row;
}
return $return;
}
?>
<?php
require 'prhlavicka.php';
pis_hlavicku('Vypis článků');
require_once 'db.php';
$kom = new server();
$sql=$kom->query("SELECT autor,nazev,obsah FROM `Clanky_Sadek`");
while ($data = mysql_fetch_row($sql)){
ECHO '<br />--AUTOR--<br />'.$data[0].'<br />__NÁZEV ČLÁNKU__<br />'.$data[1].'<br />..OBSAH ČLÁNKU..<br />'.$data[2]; }
include 'Paticka.html'; ?>
<?php
$conn=mysql_connect("localhost","root","");
if($conn)
{
echo("Connection Successfully");
$seldb=mysql_select_db("test",$conn);
if($seldb)
{
echo("Database selected successfully");
$retrive=mysql_query("select name,number from login1 where name='sateesh'",$conn);
if($retrive)
{
echo("Successfully data retrived<br>");
$result=mysql_fetch_row($retrive);
echo ("Name".$result[0]);
echo ("Number".$result[1]);
}
else
{
echo "Table not inserted";
}
}
else
{
die("database not selected");
}
}
else
{
die("connection faild");
}
mysql_close($conn);
?>
Creates table from all db info:
<?php
$qry = "SELECT * FROM exp_member_data";
$res = mysql_query($mem_qry);
function mysql_fetch_all($res) {
while($row=mysql_fetch_array($res)) {
$return[] = $row;
}
return $return;
}
function create_table($dataArr) {
echo "<tr>";
for($j = 0; $j < count($dataArr); $j++) {
echo "<td>".$dataArr[$j]."</td>";
}
echo "</tr>";
}
$all = mysql_fetch_all($res);
echo "<table class='data_table'>";
for($i = 0; $i < count($all); $i++) {
create_table($all[$i]);
}
echo "</table>";
?>
The following are the basic codes to get a specific row from the mysql db into a $row variable:
$query = "SELECT * FROM table";
$result = mysql_query($query);
$row = mysql_fetch_row($result);
And $row[0], $row[1] ... $row[n] are used to access those field values.
Does anyone know how I can add a new field to $row, so that the field count increases from n to n+1?
I have tried treating $row like an array, and tried array_push function, but didn't work.
Thanks.
