Regular expression to remove a parameter from url

Question

I have an url which looks like page.php?stuff=stuff&stuff=stuff&order=sometext&page=number

and I want to remove the "order=sometext" part. I'm using this php code :

        $link = $_SERVER['REQUEST_URI'];
        $re = "/&order=/";
        $link = preg_replace($re, "", $link);

And I'm looking for the correct pattern that should be $re to clear the "order=sometext" from the url. The "&page=number" part has to be kept when present, but isn't always there. Any ideas ?

Thanks in advance !

Yeah thanks, I just mistyped when posting my question. – Kishlin Jun 14 '16 at 14:20 — Kishlin, Jun 14 '16 at 14:20

The regex should be

(&|\?)order=[^&]+

(&|\?): the order could be first in the list, so we are removing either & or ?.

Oh. What does the (&|\?) change ? – Kishlin Jun 14 '16 at 14:23
In my situtation it will never be first but thanks anyway for the clarification. – Kishlin Jun 14 '16 at 14:25

Actually I made it work using /&order=[^&]*/. :)
