Passing JavaScript Variable to PHP Session variable

Question

I am trying to update/create session variable when I change the option thru a drop-down box. TThe value is stored in a javascript function. Can any1 tell me how I can pass this

Answer 1

The only alternative I can think of is using javascript to set a parameter in the URL which you could interpret later with PHP, but that would be after another page load.

edit: I don't think this will achive what you after on second thought, but I'll leave the answer just in-case
