php 將session記錄到redis中

1、安裝phpredis擴展

2、重寫session開放接口

<?php
/**
 * Created by PhpStorm.
 * User: kungyu
 * Date: 2015/11/24
 * Time: 17:46
 */
class sessionManage
{
    private $redis;
    private $expireTime = 3600;

    public function __construct()
    {
        $this->redis = new Redis();
        $this->redis->connect('127.0.0.1', 6379);
        session_set_save_handler(
            array($this, 'open'),
            array($this, 'close'),
            array($this, 'read'),
            array($this, 'write'),
            array($this, 'destroy'),
            array($this, 'gc')
        );
        session_start();
    }

    public function open($path, $name)
    {
        return true;
    }

    public function close()
    {
        return true;
    }

    public function read($id)
    {
        $res = '';
        if ($val = $this->redis->get($id))
            $res = $val;
        return $res;
    }

    public function write($id, $data)
    {
        $res = false;
        if ($this->redis->set($id, $data)) {
            $this->redis->expire($id, $this->expireTime);
            $res = true;
        }
        return $res;
    }

    public function destroy($id)
    {
        $res = false;
        if ($this->redis->delete($id))
            $res = true;
        return $res;
    }

    public function gc($maxLifeTime)
    {
        return true;
    }

    public function __destruct(){
        session_write_close();
    }
}

3、驗證使用

userlogin.php

include_once("./sessionManage.class.php");
$session_class = new sessionManage();
$_SESSION['username'] = 'kung';
echo $_SESSION['username'].'1111';

userlogout.php

include_once('./sessionManage.class.php');
$sess = new sessionManage();
echo $_SESSION['username'];
