note 87478 added to function.mysql-real-escape-string

for all those who would like to use a different solution other than the mysql_real_escape_string or related functions. PHP provides yet another powerful function. I always use this <?php if(!preg_match_all("/^[a-zA-Z0-9]{4,20}+$/", $_COOKIE['cookie'], $message)){ echo "<p><font color=red size=4>Username is Illegal</font></p>"; require 'index.php'; die; } else { $cookie = $_COOKIE['cookie']; } ?> You can use any user input in place of cookie for example post, get etc. Hope it comes useful for someone.
