I reported their use of eregi() WITH the NOT logical operator AGAINST $_SERVER['PHP_SELF'] is the problem not eregi() by itself
I agree using $_SERVER['SCRIPT_NAME'] is one way to fix it IF this element is available on the server. Since the manual says, "you may or may not find any of the following elements in $_SERVER," IMO it's safer to secure a file by checking whether a CONSTANT, which is defined in the calling script, exists in the called one.
