微信公众平台开发，php问题

Question

我的目的是在微信里回复一个关键词，然后公众号就从指定文件夹的txt里获取相关信息并输出（以行为单位）
但是。。。每次到 $results=get_results($q);这条语句就不行了 求大神

 <?php
define("TOKEN", "weixin");
$time_start = microtime(true);
define('ROOT', dirname(__FILE__).'/');
define('MATCH_LENGTH', 0.1*1024*1024); //字符串长度 0.1M 自己设置，一般够了。
define('RESULT_LIMIT',100);

    $wechatObj->valid();
