Proper way to retrieve data from sessionStorage in php

Question

I want to implement a code like this however i am getting an error as expected does anybody have any other way to do this or solve my error and make the code work. I have read that this can be done with AJAX but my teacher has forbidden me from using a language other than PHP javascript and html.

 <html>
 <body>
 <?php
 $user = "<script language='JavaScript'>var n=sessionStorage.getItem('user');document.write(n);</script>";

   //do something with $user
  ?>
  </body
  </html>

Answer 1

You can not retrieve sessionStorage or localStorage data (that exists on client) on server (PHP in you example). You have several options:

store data in cookies which can be retrieved on server side
send data via get http request (careful: URL limit size):
send data via post http request and hidden form field
and probably the best option, send data to server with AJAX.
