Generate Code

Post  scvinodkumar on Sat Mar 29, 2008 10:16 pm

<?php
function generateCode($length=6) {
$chars = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPRQSTUVWXYZ0123456789";
$code = "";
$clen = strlen($chars) - 1; //a variable with the fixed length of chars correct for the fence post issue
while (strlen($code) < $length) {
$code .= $chars[mt_rand(0,$clen)]; //mt_rand's range is inclusive - this is why we need 0 to n-1
}
return $code;
}
echo generateCode();
?>
