我们经常使用[Memcache][]来做数据的缓存,比如大的分布式的应用的会话数据的保存等,每次使用Memcache进行数据的操作都必须依赖于Memcache提供的API,对象的创建,方法的调用等,虽然就几个API,使用起来也挺方便的,但再没有像使用数组这么方便来使用你的Memcache了.

在PHP5里,可以方便的帮我们实现了(基于SPL).几小时的工作,可能有些小BUG,欢迎反馈.:)

    class _MEM implements ArrayAccess
    { 
        private $_data = array();

        public function __construct($host,$port = 11211)
        { 
            $this->_host = $host;
            $this->_port = $port;
            $this->_handler = new Memcache;     
     
            if (!$this->_handler->connect($host,$port))
                $this->_handler = false;
        }

            unset($this->_data[$offset]);
        }      
     
        public function offsetGet($offset)
        { 
            if (!$this->_handler)
                return false;
                        echo 'get';
            if (isset($this->_data[$offset]))
                return $this->_data[$offset];
            else
                return $this->_handler->get($offset);
        }      
     
        public function offsetSet($offset, $value)
        { 
            if (!$this->_handler)
                return false;      
     
            switch ($offset)
            { 
                case '_host':       $this->_host = $value;  break;
                case '_port':       $this->_port = $value;  break;
                case '_expire':     $this->_expire = $value;break;
                case '_compress':   $this->_host = $value;  break;
                default:
                    if (emptyempty($value) && $value != '0')
                        $this->_handler->delete($offset);
                    else
                        $this->_handler->set($offset,$value,$this->_compress,$this->_expire);
            }
             $this->_data[$offest] = $value;
        }
    }
    $_MEM = new _MEM('10.210.71.51');

举个小例子:

include_once('mem.class.php')  ;       
     
    $_MEM['dd'] = "roast";
    unset($_MEM['dd']);               //delete a memcache value
    var_dump($_MEM['dd']);                 
     
    echo $_MEM->_host;
    $_MEM['_host'] = '192.168.1.1';   //set the memcache server host
    echo $_MEM->_host;      
     
    $_MEM['roast'] = '张立冰';
    $memcache = new Memcache;
    $memcache->connect('10.210.71.51', 11211) or die ("Could not connect");
    var_dump($memcache->get('roast'));

    不错，要是php能把memcache内置就好了

    PHP的一些扩展（APC、EA、XCACHE）等可以做差不多的memcache的工作，但是不能做分布式……
