title: PHP set cookie lifetime
body: <p>I have this function to start a secure session:</p>
  
  <pre><code>function sec_session_start() {
      $session_name = 'sec_session_id'; // Set a custom session name
      $secure = false; // Set to true if using https.
      $httponly = true; // This stops javascript being able to access the session id. 
  
      ini_set('session.use_only_cookies', 1); // Forces sessions to only use cookies. 
      $cookieParams = session_get_cookie_params(); // Gets current cookies params.
      session_set_cookie_params($cookieParams["lifetime"], $cookieParams["path"],     $cookieParams["domain"], $secure, $httponly); 
      session_name($session_name); // Sets the session name to the one set above.
      session_start(); // Start the php session
      session_regenerate_id(true); // regenerated the session, delete the old one.     
  }
  </code></pre>
  
  <p>How do I set my cookies to expire whenever the user navigates away from my app or closes their browser? Basically, every time a user visits my app, they need to login again.</p>
