Welcome to SO. Please step first to HELP center, then visit GET started, and finally, read How to Ask Question and provide a MCVE : Minimal, Complete, and Verifiable Example. But keep in mind that SO is a community that helps, and no one will do all the work for you. You can read THIS — OldPadawan

@rymdmaskin, OP wants to do the opposite: passing a variable from JS to PHP. — Jordi Nebot

@JordiNebot Yes, but it is still the same idea behind it. PHP is server-side language and JavaScript in this case is Client-side. You still need to exchange data between the server and client. — rymdmaskin

You can't. As others said million times, JavaScript is Client Side Language meanwhile PHP is Server Side. You can't manipulate Server Side language via Client Side Language. You should pass your JavaScript variable to Server with AJAX and do your operation.
