title: How to check Laravel SessionID?
body: <p>I am a little confused with the session of Laravel. Laravel will start a session when client request the application and save a <code>_token</code> in the session if none of <code>_token</code> has been set.</p>
  
  <p>But when using <code>isset($_SESSION)</code> to check the session, it returns false. why cannot check laravel session by <code>isset($_SESSION)</code>?</p>
  
  <p>How can I get the Laravel <code>SessionID</code>?</p>
