Here is a little code that shows you how to create a random string in php, very handy for creating random passwords, etc.

$chars = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789";
$password = "";
for($i=0; $i<7; $i++){
     $randNum = mt_rand(0, 61);
     $password .= $chars[$randNum];
}
echo $password;

To change the length of the string simply edit the second number in the for loop.

Awesome... I've been looking for a way to do that in PHP correctly but don't understand how to append and mush things together in PHP enough to be able to do it alone.

Thanks!

In php the equivalent of what in most languages is += for strings, php uses .=

Sample:

<?php
    $myString = "";
    for($i = 0; $i < 10; $i++);
        $myString .= $i;
?>

Sample Result:

Hope that clarifies that for you.
