Question

Say I have something like:

&page=4

I want to replace this and make it blank, so it doesn’t exist.

But that page number could be anything, 66, 98, 17, 2, 109, etc.

Currently I have something along the lines of:

$currentpage = str_replace("&page=", "", $currentpage);

But I need it to also remove the number, how do I do this?

Thank you.

Answer 1

$currentpage = preg_replace("/&page=\d+/", "", $currentpage);

But if you are creating this yourself, you ought to do…

$get = $_GET;

unset($get['page']);

echo http_build_query($get);

This will output all the GET params nicely serialised a string. When you unset the page member, it obviously won’t appear 🙂
