mysql_fetch_row — Get a result row as an enumerated array
This extension is deprecated as of PHP 5.5.0, and will be removed in the future. 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:

Parameters
-

echo $row[0]; // 42
echo $row[1]; // the email value
?>

Коментарии
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.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.
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
