  • Did you try to use ajax? – Adhan Timothy Younes Apr 22 '17 at 08:16

    @rymdmaskin, OP wants to do the opposite: passing a variable from JS to PHP. – Jordi Nebot Apr 22 '17 at 09:25
  • @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 Apr 22 '17 at 09:56

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.
