title: Telling a php session's name?
body: <p>I installed a pre-built forum on my website and I want (in a diffrent page) to check if the forum's session is active.<br>
  Something like :</p>
  
  <pre><code>if (isset($_SESSION['forum'])) { echo "Session is active!"; }
  </code></pre>
  
  <p>Problem is - I don't know the sessions name...
  Tried downloading some chrome add-ons for session managing but I can't get the name of the session.</p>
  
  <p>Whats the right way of doing this?<br>
  Thanks ahead!</p>
