日志记录类库 LogUtil.class.php

 

<?php
/**

 */
class LogUtil{
	public static function writeLog($text){
		// 调用 error_log() 的另一种方式:
		error_log($text."\r\n", 3, "./my-errors.log");

接下来就可以写控制器了

define("TOCKEN", "huigood520");       //定义TOCKEN常量  与微信公众号配置的一致

        //echo $token;
    	$WeiXin->valid();
    	$reply = $WeiXin->responseMsg($postStr);
    }
