// 确保已经安装了libmemcached

wget http://pecl.php.net/get/memcached-2.1.0.tgz
tar zxf memcached-2.1.0
cd memcached-2.1.0
phpize
./configure
make 
make install 

// 修改 php.ini
// vim .../php.ini
// 添加扩展

php-memcached.php

<?php

//连接
$mem = new Memcached();
$mem->addServer("127.0.0.1", 11211);
//$mem->connect("127.0.0.1", 11211);

//保存数据
$mem->set('key1', 'This is first value', 60);
$val = $mem->get('key1');
echo "Get key1 value: " . $val ."<br />";

//替换数据
$mem->replace('key1', 'This is replace value', 60);
$val = $mem->get('key1');
echo "Get key1 value: " . $val . "<br />";

//保存数组
$arr = array('aaa', 'bbb', 'ccc', 'ddd');
$mem->set('key2', $arr, 60);
$val2 = $mem->get('key2');
echo "Get key2 value: ";
print_r($val2);
echo "<br />";

//删除数据
$mem->delete('key1');
$val = $mem->get('key1');
echo "Get key1 value: " . $val . "<br />";

//清除所有数据
$mem->flush();
$val2 = $mem->get('key2');
echo "Get key2 value: ";
print_r($val2);
echo "<br />";

//关闭连接
//$mem->close();

ruby有gem，python有easy_install 以及进阶的pip，新兴的nodejs也有npm。。。

php啊！！！
