How to manage a session

      cookie $name = session_name(); // By default, PHPSESSID
      

      $id = session_id(); // For example, l1jef1foi1g8u6qnui4f8b6e14
      

      session_id('abc123');
      

      $_SESSION = array(); // Clear session data from memory
      session_destroy(); // Clean up the session ID
      

       $name = session_name();  // Get name of session cookie
       $expire = strtotime('-1 year');  // Create expire date in the past
       $params = session_get_cookie_params();  // Get session params
       $path = $params['path']; 
       $domain = $params['domain']; 
       $secure = $params['secure']; 
       $httponly = $params['httponly']; 
       setcookie($name, '', $expire, $path, $domain, $secure, $httponly);
      

Description

• A session ends when the user closes the browser, when a specified amount of time elapses without a request, or when the code calls the session_destroy() function.
• To remove all data associated with the session from the client and the server, you can clear the session data from memory, call the session_destroy() function, and use the setcookie() function to delete the session cookie.
• The session_name() function gets the name of the session cookie. By default, the session cookie has a name of "PHPSESSID"<./li>
• The session_get_cookie_params() function gets an associative array that contains all of the parameters for the session cookie.
