PHP模块memcached使用指南,memcached使用指南

1.添加扩展包

    php_memcache.dll

2.在PHP.INI添加

    extension=php_memcache.dll

3.程序

复制代码 代码如下:


    //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,MEMCACHE_COMPRESSED,60)){
        echo '添加ok';
    }*/
    //3.添加数组
    //在添加数组是,根据需要. 希望序列号放入  ,
    //serializeunserialize, 如果根据需要,也可以json_encode json_decode
    $arr=array("bj",'tj');
    if($mem->set('key1',$arr,MEMCACHE_COMPRESSED,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',$dog1,MEMCACHE_COMPRESSED,60)){
        echo '添加对象ok';
    }*/
    //5.添加null 布尔值
/*    if($mem->set('key1',false,MEMCACHE_COMPRESSED,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($con);
    echo "
";
    if($mem->set('key1',$con,MEMCACHE_COMPRESSED,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',MEMCACHE_COMPRESSED,60)){
        echo 'replace ok';
    }else{
        echo 'replace no ok';
    }

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

总结:

1.      mem服务的数据不是同步的, 数据是分布的

2.      把什么数据放入到哪个memcached是由客户端的mem对象决定

3.      当执行addServer的时候,并不是立即去连接mem服务,而是通过计算,hash后才去决定连接哪个mem服务,因此当你大量加入服务器到连接池,没有多余开销
