比较完整的微信开发php代码

本文实例为大家分享了微信开发php代码，供大家参考，具体内容如下

appid = $appid;
      $this->appsecret = $appsecret;
    }
 
    //验证服务器地址有效性
    public function valid()

      $timestamp = $_GET['timestamp'];//时间戳
 
      $nonce = $_GET['nonce'];//随机数
 
      //二、加密/校验过程
      // 1. 将token、timestamp、nonce三个参数进行字典序排序；
      // bool sort ( array &$array [, int $sort_flags = SORT_REGULAR ] ) 对数组排序 

      $tmpArr = array(TOKEN,$timestamp,$nonce);//将上面三个参数放到一个数组里面
      sort($tmpArr,SORT_STRING);
 
      // 2. 将三个参数字符串拼接成一个字符串进行sha1加密；
      $tmpStr = implode($tmpArr); //将数组转化成字符串
 
      $signatureStr = sha1($tmpStr);
 
      // 3. 开发者获得加密后的字符串与signature对比。
