javascript is a client-side language, while php is a server-side
language... the value you are passing to $width only exists on the
client side, therefore the php server-side boolean fails.

i think you will have to pass the client-side calculated variable of
screen.width to the php server before you can do this properly,
probably through a POST form or GET request. nice idea, though
(dynamically loading css based on screen resolution).
