Random number generating function manual page: http://www.php.net/rand

To get your 5 character string you'll want to do something along the
lines of:

$x = '';
for($i = 0; $i < 5; $i++) {
$x .= chr(rand(97, 122));
}

Your function is mt_rand(). The manual page includes some user comments you
can just copy & paste. Don't forget to generate a 'random' seed with
mt_srand().
