PHP Push 服务器端代码

	function server() {
		for ($i = 0, $timeout = 10; $i < $timeout; $i++) {
			if (connection_status() != 0) {
				exit();
			}
			$where = array();
			$user_id = $user_id = get_user_id();
			session_write_close();
			$where['user_id'] = $user_id;
			$where['time'] = array('elt', time() - 1);
			$model = M("Push");
			$data = $model -> where($where) -> find();
			$where['id'] = $data['id'];
			//dump($model);
			if ($data) {
				sleep(1);
				$model -> where("id=" . $data['id']) -> delete();
				$this -> ajaxReturn($data['data'], $data['info'], $data['status']);
			} else {
				sleep(2);
			}
		}
		$this -> ajaxReturn(null, "no-data", 0);
	}
