Set a php variable according to a javascript condiitional

[Andres Vaquero]

Hello all, I'm new to php and javascript and what not... but hopefully there is someone out there that has an answer.

With jquery I detect screen resolution. I set a conditional : if screen is bigger than... and smaller than... then...

Now if that conditional is given I want to set a php variable. How?

Any guidance would be greatly appreciated.

php runs on the server, js runs on the client, so in general you can't

So say you need to detect the resolution of a browser and according to that you need to load one image or another. How would you go about it?

Load a default image (or placeholder, possibly hidden) and have JS replace it when it works out the screen size.
