php session 存储到redis里，转

session.save_handler = redis

session.save_path ="tcp://127.0.0.1:6379"

ini_set("session.save_handler","redis");

ini_set("session.save_path","tcp://127.0.0.1:6379");

<?php

// 如果未修改php.ini下面两行注释去掉

// ini_set('session.save_handler', 'redis');

// ini_set('session.save_path', 'tcp://127.0.0.1:6379');

session_start();

$_SESSION['sessionid'] ='this is session content!';

echo$_SESSION['sessionid'];

echo'<br/>';

$redis=newredis();

$redis->connect('127.0.0.1', 6379);

// redis 用 session_id 作为 key 并且是以 string 的形式存储

echo$redis->get('PHPREDIS_SESSION:'. session_id());
