[HELP] How to redirect users to a different URL on mobile & desktop?

A few years ago I used a simple redirect PHP script that redirects users entering my URL to totally different URLs based on if they entered this on a mobile or desktop device.

The script was written in such a way that I could just replace the links in it to make this work with a code looking like a:

if mobile; mymobilesite.com

else; mydesktopsite.com

Now I'm searching for such a thing but I can't find it. I can only find a script that displays the different variations of the site on mobile devices but I want the domain name to be JUST A REDIRECT that is forwarding the traffic to 2 splited different URLs of different websites. Can someone share with me this kind of working PHP URL redirection script?

Well there are cloakers that do this but if you don't wanna spend $ , it shouldn't be too hard to search for "conditional redirects php'" or your favorite language

I found this - it seems to be the shortest. Look at the first answer.

You do not need to test for desktop, the mobile redirect doesn't occur on dektop.
