Memcached之PHP调用

    <?php  
    $memcache = new Memcache; //创建一个memcache对象  
    $memcache->connect('localhost', 9023) or die ("Could not connect"); //连接Memcached服务器  
    $memcache->set('key', 'Hello,XiFeiJian'); //设置一个变量到内存中，名称是key 值是test  
    $get_value = $memcache->get('key'); //从内存中取出key的值  
    echo $get_value;  
    ?>  

    <?php  
    //连接Memcache  
    $mem = new Memcache;  
    $mem->connect("localhost", 11211);  
    //保存数据
