`

  public function GetZkNodeData($svrIp, $path, &$msg){

	$zc = self::GetZkClient($svrIp, $msg);

	if (is_null($zc)){
		return "";
	}
	if (($data = $zc->get($path)) !== false){
		return $data;
	}

	$msg = "err!";
	return "";
 }

public static function GetZkClient($svrIp, &$msg){
	try{
		$zc = new ZookeeperClient();
		$zc->connect($svrIp);
	} catch(\Exception $e){
		$msg = $e->getMessage();
		return null;
	}
	return $zc;
}
