JavaScript variable to PHP variable?

Is it such easy or just not possible??? Do ia have to use AJAX ?(noob)

I have a Javascript variable:

var UserID = 1;

I want to use the UserID for an already loaded/created PHP -Array. HOW ?

Hiya,

Yep ajax is the way, your converting from client side to server side code.

You could easily make a javascript value from php by echoing out script but not the other way around

Okay, so i was right… i really have to learn AJAX ..thanks!

Just use jQuery. It makes life a lot easier

$.post('file.php',{'userid':1},function(data){
     console.log(data);
});
