How do I set a SESSION variable to equal the value of a JavaScript variable?

I need to set some PHP SESSION variables to equal the value in some JavaScript variables. How do I go about doing this?

If I have var jsVariable = “somestring” and $_SESSION[‘phpVariable’], how could I set the latter to equal the former? This has been bothering me for years! ?

Thanks,

@MindzaiMay 27.2009 — Since PHP is executed server side and javascript is executed (almost always) client side, you will need to send a request to a php script containing the value retrieved via js, using either GET or POST usually. If you need to do this without reloading the whole page you can use AJAX.

@multimediocrityauthorMay 27.2009 — Thanks. I am not an AJAX wiz, and I haven't used it for a couple years. Even then I didn't fully understand the concepts. Can you recommend me to some code or post it here that would allow me to do this simple transfer of variable data?

I don't mind reloading the page either. I work often with GET and POST. I have about 50 variables that I need to change over (because it's an array). Each variable will probably have about 50 characters. Is there a limit to how much data I can send using GET or POST at one time?

Thanks,

Multimediocrity.
