什么是将Zend2应用程序与PHPBB3身份验证集成在一起的正确方法？

请看看：

您可以实现为您的Zend框架项目创建提供程序的界面.

创建会话后,可以看到提供者如何使用

https://github.com/phpbb/phpbb/blob/master/phpBB/phpbb/session.php#L560

/* @var $provider_collection phpbbauthprovider_collection */
    $provider_collection = $phpbb_container->get('auth.provider_collection');
    $provider = $provider_collection->get_provider();
    $this->data = $provider->autologin();

确保两个项目都使用相同的Cookie,或者zend也在设置用户登录时的phpBB Cookie和会话,session_start使用它来查找会话ID：

if ($request->is_set($config['cookie_name'] . '_sid',phpbbrequestrequest_interface::COOKIE) || $request->is_set($config['cookie_name'] . '_u',phpbbrequestrequest_interface::COOKIE))
    {
        $this->cookie_data['u'] = request_var($config['cookie_name'] . '_u',false,true);
        $this->cookie_data['k'] = request_var($config['cookie_name'] . '_k','',true);
        $this->session_id       = request_var($config['cookie_name'] . '_sid',true);

        $SID = (defined('NEED_SID')) ? '?sid=' . $this->session_id : '?sid=';
        $_SID = (defined('NEED_SID')) ? $this->session_id : '';

        if (empty($this->session_id))
        {
            $this->session_id = $_SID = request_var('sid','');
            $SID = '?sid=' . $this->session_id;
            $this->cookie_data = array('u' => 0,'k' => '');
        }
    }
    else
    {
        $this->session_id = $_SID = request_var('sid','');
        $SID = '?sid=' . $this->session_id;
    }

谢谢.
