ThinkPHP框架中使用Memcached缓存数据的方法

 public function set($name, $value, $expire = null) {
  N('cache_write',1);
  if(is_null($expire)) {
   $expire = $this->options['expire'];
  }
  $name = $this->options['prefix'].$name;
  if (empty($expire))
   $time = 0;
  else
   $time = time() + $expire;
  if($this->handler->set($name, $value, $time)) {
   if($this->options['length']>0) {
    // 记录缓存队列
    $this->queue($name);
   }
   return true;
  }
  return false;
 }

//缓存配置
 'DATA_CACHE_TYPE' => 'Memcached',
 'MEMCACHED_SERVER' => array(
  array('127.0.0.1', 11211, 0)
 ),

Memcached::addServers(array)

Memcached::setOptions(array)
