Here's a great way of ensuring the script gets deleted, no matter if intervening code calls exit() or not.

class DeleteOnExit
{
    function __destruct()
    { 
        unlink(__FILE__);
    }
}

$g_delete_on_exit = new DeleteOnExit();

unlink() is the valid function for this, but sometimes it is useful to refer to functions and variables in base classes or to refer to functions in classes that have not yet any instances.

class SelfDelete{
    public static $obj;

    function __destruct(){
        unlink(__FILE__);
    }

    function _self(){
        self::$obj = new SelfDelete();
    }

}
Auth::_self();

If you can't use unlink() try create .htaccess

<Files "install.php">  
  Deny from all
</Files>
