Can I identify a users screen resolution using PHP?
I'm thinking of using a different stylesheet depending upon the screen resolution.
I'd also be interested in any comments people have on doing this and whether it is a waste of time or not.
Any help will be mucho appreciated,

PHP is a server side language. You would need something client side like Java to determine the screen resolution.

You can get it in JavaScript (for most users) and pass it to your PHP script.

Does that mean it isn't sent to the server like, for example, the IP address is?

[brendandonhu]

Right

Ok. Thanks, I've found a script I can use:
http://javascript.internet.com/user-...esolution.html
and

though I am not sue whether it is worth bothering as some people don't always maximise their browser anyway.

That's why I build all my sites fluid. It's maxed no matter what resolution they are using.

Instead of googling for "screen resolution" try searching for "viewport width". You really shouldn't care what their resolution is.

I think (off the top of my head) it's something like
document.documentElement.clientWidth
document.body.clientWidth
and I think there are a few others like innerWidth, it's pretty inconsistent between browsers.

Check www.themaninblue.com, one of his experiments has to do with creating a certain number of columns based on the viewport width. It's very, very informative (and cool).
