You should read through the manual:
http://us.php.net/manual/en/refs.basic.vartype.php
Specifically:
http://us.php.net/manual/en/ref.var.php
And try the search in the manual. For example, search for "integer".

see i am using
and $MaxBarcode is CCEFFD3456740001
preg_match("/([0-9]*)/",$MaxBarcode,$match);
i want to extract 3456740001 but this preg_match("/([0-9]*)/",$MaxBarcode,$match); is not getting me that but preg_match("/([0-9]*$)/",$MaxBarcode,$match); it is getting me 3456740001 why and i know '$' represents "ends with" but preg_match is supposed to match whole $MaxBarcode right?
