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.:)
/**
* mem.class.php -- Class used to access memcache server as array.
*
* Written by roast (roast_AT_php_DOT_net).
*
* Feel free to email me with questions/bugs.
* If you find this useful, would be great to hear from you.
*
* version 1.0 -
*
* Changes:
*- First release.
*
* Example:
*
* include("mem.class.php");
*
* //global variable $_MEM
*
* $_MEM['dd'] = "roast";//memcache::set
* unset($_MEM['dd']); //memcache::delete
*
* var_dump($_MEM['dd']);
*
* Notes:
*- Protect keys of memcache: _host/_port/_compress/_expire.
*- PHP version 5.0+

class _MEM implements ArrayAccess
{
private $_data = array();
private $_handler = false;
public$_host;
public$_port = 11211;
public$_compress = false;
public$_expire = 30;
public function __construct($host,$port = 11211)
{
$this->_host = $host;
$this->_port = $port;
$this->_handler = new Memcache;
if (!$this->_handler->connect($host,$port))
$this->_handler = false;
}
public function offsetExists($offset) {}
public function offsetUnset($offset)
{
$this->_handler->delete($offset);
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'));

5月 8th, 2008 at 12:48 下午 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……
