What I want to know if it is possible (and if so how to implement it) is this:

Pick a random password from an array and change ever 24 hours OR when a user uses the password, show admins and mods password so they do not have to look around.

I was thinking that this will probably require MySQL for the User Database but I have no idea where to even start, I thought this idea was interesting so if you can help it is appreciated.

w3school has got nice articles for php bginners and php.resourceindex.com and hotscripts.com are the places where you can look for readymade scripts.

Please read array_rand() at
ca3.php.net

example for selecting a random value from an array

<?php
srand((float) microtime() * 10000000);
$input = array("Neo", "Morpheus", "Trinity", "Cypher", "Tank");
$rand_keys = array_rand($input, 2);
echo $input[$rand_keys[0]] . "\n";
echo $input[$rand_keys[1]] . "\n";
?>
