PHP微信公众号自动发送红包API

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

class wechat_packet{
private $url = 'https://api.mch.weixin.qq.com/mmpaymkttransfers/sendredpack';//请求URL
private $mch_id;//商户号
private $weixin_appid;//公众账号appid
private $send_name;//商户名称
private $total_num = 1;//发送红包总人数
private $wishing;//红包祝福语
private $client_ip;//调用接口的机器Ip地址
private $act_name;//活动名称
private $remark;//备注信息
private $nonce_str;//随机字符串，不长于32位
private $api_password;
private $arraytoxml;//数组转xml

自动判断把gbk或gb2312编码的字符串转为utf8
能自动判断输入字符串的编码类，如果本身是utf-8就不用转换，否则就转换为utf-8的字符串
支持的字符编码类型是：utf-8,gbk,gb2312
@$str:string 字符串

数组转xml:arraytoxml.php
