获取PHP中的上一页名称（不是整个URL）

Question

I have a URL like this;

http://www.mydomain.co.uk/blist.php?prodCodes=NC023-NC022-NC024-NCB33&customerID=NHFGR

Which i grab using HTTP Referrer. The trouble is i only need the page name i.e. blist.php from the link, not the entire URL as is default using:

$_SERVER['HTTP_REFERER']

Can anyone give me an idea on how to grab that part of the URL?

Answer 1

This seems to work, but there might be other elegant url functions.

$url = 'http://www.mydomain.co.uk/blist.php?prodCodes=NC023-NC022-NC024-NCB33&customerID=NHFGR';

preg_match('/\/[a-z0-9]+.php/', $url, $match);

$page = array_shift($match);

echo $page;
