用Memcache缓存加速Mysql的查询,很不错的接口，希望对大家有所帮助！

      connect($memcachehost,$memcacheport) \	or die ("Could not connect");$query="select * from user limit 10";$key=md5($query);if(!$memcache->get($key)){        $conn=mysql_connect("192.168.30.1","root","passwd");        mysql_select_db(users);        $result=mysql_query($query);        while ($row=mysql_fetch_assoc($result))        {            $arr[]=$row;        }        $f = 'db';        $memcache->add($key,serialize($arr),0,30);        $data = $arr ;}else{        $f = 'mem';    $data_mem=$memcache->get($key);    $data = unserialize($data_mem);}echo $f;echo "";//print_r($data);foreach($data as $a){        echo $a[user_id]._.$a[email];        echo "";}?>

完成！
