ZF2的Session处理

来源：互联网发布：硬币摇卦的正确算法编辑：程序博客网时间：2024/06/11 14:57

ZendFramework之中，可以有多种办法去处理session。
这些全部都以session handler的设置而不同
一般情况下默认是以文件形式存储的
当然如果你要建立高性能网站
或许你会采用用缓存的形式来处理session
在zf2的session manager中，默认的session handler是通过一次设置以后而改变默认的
也就是说。你一旦改变了handler，那么下次还是会用这个handler来处理。
我这里是一段代码，用memcache去处理session
这个是在

                $config= $sm->get('Config');
                $sessionConfig= $config['session'];
                $saveHandler= $sessionConfig['save_handler'];
                switch($saveHandler) {
                    case'Cache':
                        $cache= $sm->get('MyCache');
                        $sessionCache= clone $cache;
                        $sessionCache->getOptions()->setNamespace('mysession')->setTtl($sessionConfig['expiration']);
                        $saveHandler= new Cache($sessionCache);
                        $manager= new ZendSessionManager();
                        $manager->setSaveHandler($saveHandler);
                        return$manager;
                        break;
                }
            },
 
            'Account\Helpers\Captcha'=> function($sm) {
                $sessionManager= $sm->get('MySessionManager');
                $captcha= new Captcha\Captcha($sessionManager);
                return$captcha;
            },
    );

如果调用了验证码的服务，那么这套session体系才会运转，否则这套session体系就不运转。
