generate a 32 length random string

[pouncer]

Hey guys, I want to generate a 32 length string which contains both number 0-9 and letter A-Z

 

letters must be caps, any ideas guys?

Here's one method:

<?php
$str = '0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ';
$randstr = '';
while (strlen($randstr) < 32)
     $randstr .= $str{rand(0,strlen($str))};
echo '[' . strlen($randstr) . '] ' . $randstr;
?>

Another:

 

<?php

$random = rand(-1000000, 1000000);
$md5 = md5($random);
$string = strtoupper($md5);

echo $string;

?>
