Is it possible to change the value of a variable using an event?

[drayarms]

Hello all. Well the topic pretty much sums up the problem. I’m pretty familiar with using events to alter the value of an html tag or attribute via the DOM. I was wondering if it is possible to use an event to alter the value of a variable within. Well I wrote the script below to test that and sure enough it didn’t work. So if by some chance it is possible to use events to do alter the value of a variable, how does one go about that?[php]

<?php $variable = "1"; echo "

Click here to change value to 2

"; echo $variable; ?>

[/php]

Javascript cannot directly alter the value of a PHP variable, as PHP is processed on the server - output sent to the browser, then the javascript is processed.

It is possible however to do so via an AJAX request.
