放到TP的Extend/Driver/Cache下，在config.php里配置'DATA_CACHE_TYPE' => 'Memcached',<br> // 'PERSISTENTID'=>'tp',//可选<br> 'MEMCACHED_HOST' => array('127.0.0.1','127.0.0.1'),<br> 'MEMCACHED_PORT' => array('11211','11212'),<br> // 'MEMECACHED_WEIGHT' => array(33,67),//可选使用：和其它缓存一样直接使用S方法就可以S('userName','wahaha',20);<br>         echo 'userName=='.S('userName');<br>         S('user1','wahaha-1',60);<br>         S('user2','wahaha-3',60);<br>         S('user3','wahaha-4',60);<br>         S('user5','wahaha-5',60);<br>         <br>         echo '<br>user1='.S('user1');<br>         echo '<br>user2='.S('user2');<br>         echo '<br>user3='.S('user3');<br>         echo '<br>user5='.S('user5');<br>         // <br>         $memcached = new CacheMemcached();<br>         $data = array(<br>             'key1' => 'value1',<br>             'key2' => 'value2',<br>             'key3' => 'value3',<br>             );<br>         $memcached->setMulti($data,60);<br>         <br>         $key = array('key1','key2','key3');<br>         <br>         p($memcached->getMulti($key));<br>         <br>         $memcached->rm('key2');<br>         <br>         p($memcached->getMulti($key));<br>         <br>         $memcached->set('key88','value88',60);<br>         <br>         p($memcached->get('key88'));<br>         <br>         $memcached->clear();<br>         <br>         p($memcached->getMulti($key));
