How Can I Get a JavaScript Variable\'s Value in PHP?

Getting JavaScript Variable Values in PHP

To access the value of a JavaScript variable in PHP, it's necessary to send that value to PHP using an intermediary means.

One approach is to set the variable value as a cookie in JavaScript:

document.cookie = "profile_viewer_uid=1";

This creates a cookie named "profile_viewer_uid" with the value "1".

In PHP, this cookie can be accessed as follows:

$profile_viewer_uid = $_COOKIE['profile_viewer_uid'];

This approach allows you to obtain the JavaScript variable value without relying on POST variables or HTML output.
