javascript - Get localStorage value into php

I have a variable set in localStorage and I want to get it into php. When php is executed the value is already set in local storage, but how should I get into php?

I tried something like this:

  $myvar = "";

But this for some reasons gives a Uncaught SyntaxError: missing ) after argument list

How should I approach this? Thanks.

You can not directly get a localStorage value in PHP, when script is executed, because localStorage is contained in user's browser, and PHP is running on server. However, you can send the value from localStorage to a server with GET or POST request.
