PHP模块memcached使用指南

<?php
??? //创建一个mem对象实例
??? $mem=new Memcache;
??? if(!$mem->connect("10.18.110.213",11211)){
??????? die('连接失败!');
??? }
??? //增加
??? //1.增加一个字串
/*??? if($mem->set('key1',"beijing",MEMCACHE_COMPRESSED,60)){
??????? echo '添加ok';
??? }*/
??? //2.添加数值
/*??? if($mem->set('key1',100,60)){
??????? echo '添加ok';
??? }*/
??? //3.添加数组
??? //在添加数组是,根据必要. 希望序列号放入?,
??? //serialize<=>unserialize,如果根据必要,也可以json_encode <=> json_decode
??? $arr=array("bj",'tj');
??? if($mem->set('key1',$arr,time()+31*3600*24)){
??????? echo '添加数组ok99111';
??? }
??? //4.添加对象
/*??? class Dog{
??????? public $name;
??????? public $age;
??????? public function __construct($name,$age){
??????????? $this->name=$name;
??????????? $this->age=$age;
??????? }
??? }
??? $dog1=new Dog('小狗',50);
??? if($mem->set('key1',$dog1,60)){
??????? echo '添加对象ok';
??? }*/
??? //5.添加null 布尔值
/*??? if($mem->set('key1',false,60)){
??????? echo '添加布尔ok';
??? }*/
??? //6. 资源类型放入.
/*??? $con=mysql_connect("127.0.0.1","root","root");
??? if(!$con){
??????? die('连接数据库失败');
??? }
??? var_dump($con);
??? echo "<br/>";
??? if($mem->set('key1',$con,60)){
??????? echo '添加资源ok';
??? }*/

??? //查询
??? $val=$mem->get('key1');
//修改
??? //可以使用replace
??? if($mem->replace("key11",'hello',60)){
??????? echo 'replace ok';
??? }else{
??????? echo 'replace no ok';
??? }

??? //删除
??? echo "<br/>";
??? if($mem->delete('key14')){
??????? echo 'key14 删除';
??? }else{
??????? echo 'key14不存在';
??? }
