本文实例为大家分享了PHP微信公众号自动发送红包API代码，分享给大家供大家参考。具体如下：
贴出核心接口代码至于数据自己填写，接口测试ＯＫ
wechat_packet.PHP

后期还是会增加在一起的把这个CLASS做起来，网上资源很多，但是都是有一定基础的人去看看改改可以，对于没有接触刚刚接触的新手还是需要给予支持的。帮助用户屡屡思路。
根据微信高级红包接口，开发PHP版本的API接口，现在进行主要代码分析。
获取随机字符串方法：
签名算法：

"); } $commonUtil = new CommonUtil(); ksort($this->parameters); $unSignParaString = $commonUtil->formatQueryParaMap($this->parameters,false); $md5SignUtil = new MD5SignUtil(); return $md5SignUtil->sign($unSignParaString,$commonUtil->trimstring(PARTNERKEY)); }catch (SDKRuntimeException $e) { die($e->errorMessage()); }
