Zend Framework实现将session存储在memcache中的方法

大佬教程收集整理的这篇文章主要介绍了Zend Framework实现将session存储在memcache中的方法，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。

本文实例讲述了Zend Framework实现将session存储在memcache中的方法。分享给大家供大家参考，具体如下：

在zend framework中，已经可以将session存储在数据库中了，不过还@L_122_3@memcache，我简单得实现了一下。

下面是SaveHandler，文件名为 ：Memcached.PHP ，将其放在 /Zend/Session/SaveHandler 目录下，代码如下(需要有PHP_memcache支持,因为字符长度限制,我把部分注释去掉了):

 The id of the current session
   *   sessionName   => The name of the current session
   *   sessionSavePath => The save path of the current session
   *
   * modified      => (String) Session last modification time column
   *
   * lifetime     => (Integer) Session lifetime (optional; default: ini_get('session.gc_maxlifetime'))
   *
   * overrideLifetime => (Boolean) Whether or not the lifetime of an exisTing session should be overridden
   *   (optional; default: falsE)
   *
   * @param Zend_Config|array $config   User-provided configuration
   * @return void
   * @throws Zend_Session_SaveHandler_Exception
