Question

I have been looking around now for a while, and I have spent a good amount of time with trial and error, and still can’t get things right :/

What I am trying to do is take a string like a url:

www.something.com/something.html?user=1&page=1

and remove the "&page=1" out of the string. This string may have another &variable after "&page=*", so I would like it to only remove the "&page=*".

What I have been trying is:
$url = preg_replace("/&page=\.{*}&?/","",$url);

so in other words: "&page=" + anynumber + till end of number or next "&"

Any ideas?

Thanks!

Answer 1

preg_replace('/&page=[^&#]*/', '', $url)

This matches &page= followed by 0 or more (that’s the * bit) characters that aren’t & or #. [...] stands for a set of characters; [^...] inverts the set.

In other words, it will match everything after &page= up to the next & or # (or end of string).
