<snip javascript and PHP>
You're somewhat out of luck, as the chain of events in your typical HTTP
transaction looks something like this...
---->[time]--------------------------------->
client request received from browser
|
+-> PHP code executed on server
|
+-> text output to webserver (including javascript source)
|
+-> [drawing of cloud representing internet]
|
+-> text input to web browser on client side
|
+-> javascript executed by client
---->[time]--------------------------------->
...The only way to have the javascript affect the PHP, is to make a
subsequent request /back/ to the server after the javascript has started
executing. You can, for example, package the screen size into a GET
variable appended to an image request.
