如何用PHP检测当前页面？

Question

I need to detect page to do some styling on a website, right now I'm using

$currentpage = $_SERVER['REQUEST_URI'];

but this returns something like /development/en/contact.php
I would like something that will only return contact.php
is there a method to achieve this?

Answer 1

basename($_SERVER['SCRIPT_NAME']);

It will return only the file and strips the folders. For more information see basename()

Note the usage of SCRIPT_NAME instead of REQUEST_URI as REQUEST_URI may contain additional "crap":

http://example.com/dev/en/contact.php/this/is/crap
REQUEST_URI: /dev/en/contact.php/this/is/crap
SCRIPT_NAME: /dev/en/contact.php
