title: 8hours renamed php session lost data after 30 minutes
body: <p>My default PHP session is 30 minutes.</p>
  
  <p>I got this first code :</p>
  
  <pre><code>&lt;?php
  session_set_cookie_params(28800);
  session_name('TEST');
  session_start();
  session_regenerate_id(true);
  
  $_SESSION['test'] = 'jam';
  ?&gt;
  </code></pre>
  
  <p>And this second one :</p>
  
  <pre><code>&lt;?php
  session_set_cookie_params(28800);
  session_name('TEST');
  session_start();
  session_regenerate_id(true);
  
  echo $_SESSION['test'];
  ?&gt;
  </code></pre>
  
  <p>The fact is, my session is lost after 30 minutes without activity.</p>
  
  <p>Timed example :</p>
  
  <pre><code>00:00 : run first script
  00:10 : run seconde script : i got "jam"
  00:20 : run seconde script : i got "jam"
  00:40 : run seconde script : i got "jam"
  01:11 : run seconde script : session is lost
  </code></pre>
  
  <p>Hope you can give me any clue to fix this.</p>
