Redis如何保存數組和對象

我們可以封裝一個自己的Redis類

 

<?php
class MyRedis{ private static $handler; private static function handler(){ if(!self::$handler){ self::$handler = new Redis(); self::$handler -> connect('127.0.0.1','6379'); } return self::$handler; } public static function get($key){ $value = self::handler() -> get($key); $value_serl = @unserialize($value); if(is_object($value_serl)||is_array($value_serl)){ return $value_serl; } return $value; } public static function set($key,$value){ if(is_object($value)||is_array($value)){ $value = serialize($value); } return self::handler() -> set($key,$value); } }

<?php
require_once 'MyRedis.php'; class MyObj{ public function rTime(){ return time(); } } $arr = array(1,2,3); $obj = new MyObj(); $str = ' My name is Jeffrey.'; MyRedis::set('arr',$arr); MyRedis::set('obj',$obj); MyRedis::set('str',$str); $_arr = MyRedis::get('arr'); $_obj = MyRedis::get('obj'); $_str = MyRedis::get('str');
 var_dump($_arr); var_dump($_obj->rTime()); var_dump($_str);
