Memcached分布式部署方案设计（含PHP代码）

php代码

<?php
function test($key='name'){
    $md5 = substr(md5($key), 0, 8);
    $seed = 31;
    $hash = 0;
    for($i=0; $i'192.168.1.2', 'port'=>6379),
        array('host'=>'192.168.1.3', 'port'=>6379),
        array('host'=>'192.168.1.4', 'port'=>6379),
        array('host'=>'192.168.1.5', 'port'=>6379),
);
$key = 'username';
$value = 'lane';
//根据KEY获取hash
$hash = $this->test($key);
$count = count($mamcacheList);
$mamcache = $mamcacheList[$hash % $count];
$mc = new Mamcached($mamcache);
$mc->set($key, $value);
?>
