title: Session variable resets on refresh
body: <p>I have a session variable 'touser' which resets everytime I refresh the page but my session variable for the whole session "user" does not reset.</p>
  
  <pre><code>&lt;?php 
  session_start(); require("source/header.php");
  require("scripts/connection/signup/db.php");
  ?&gt;
  
  &lt;?php 
  session_start();
  $touser=$_POST["chats"];
  $_SESSION["touser"]=$touser;
  echo $_SESSION["touser"];
  ?&gt;
  </code></pre>
