php 如何以json格式儲存session，而不是預設的內建編碼？
折騰了下，即使session_save_handler被自己的類別或方法重寫，write與read的出入資料都還是被序列化的，而且被session序列化不是一般的序列化...還是不能解解決memcached保存session數據為json的格式

php 如何以json格式儲存session，而不是預設的內建編碼？
折騰了下，即使session_save_handler被自己的類別或方法重寫，write與read的出入資料都還是被序列化的，而且被session序列化不是一般的序列化...還是不能解解決memcached保存session數據為json的格式
找到了方案：
<code><?php

/**
* Memcached JSON-formatted session save handler
*
* The default memcache session save handler stores sessions encoded with
* session_encode, but the encoded session is not simple to parse in other
* languages. Therefore, this class encodes the session in JSON to make reading
* the session in other languages simple.
*
* Note: This class uses the newer php-memcached extension, not php-memcache!
* @see http://php.net/manual/en/book.memcached.php

可以考慮下寫庫
