Writing an user service that use the session interface:
UserService.php
namespace Usage; use Interop\Session\SessionInterface; class UserService { public function isConnected(SessionInterface $session) { if ($session->has("userId")) { return true; } return false; } public function login(SessionInterface $session, $userId) { if ($this->isConnected($session)) { return false; } $session->set("userId", $userId); return true; } public function logoff(SessionInterface $session) { if ($this->isConnected($session)) { $session->remove("userId"); return true; } return false; } }
Use the implementation:
Index.php
use Interop\Session\Utils\ArraySession\ArraySession; use Usage\UserService; require_once("vendor/autoload.php"); session_start(); $userId = 1; $userService = new UserService(); $session = new ArraySession($_SESSION, "myprefix"); // Check if the user is connected if ($userService->isConnected($session)) { // logoff the user $userService->logoff($session); } else { // login the user $userService->login($session, $userId); }
