  ";}}?>

The error section has been marked in red and changed to '/class/I' before it becomes normal... isn't the preg_match_all function parameter not available to use variables ????

------ Solution --------------------
$ Search = "/class/I"; // you can do this.
------ Solution --------------------
Glob ("./* {$ search2} *"); can also solve your problem
