我是靠谱客的博主舒服板凳，最近开发中收集的这篇文章主要介绍微信发红包 PHP 实现，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

首先你的有个服务号,并且开通了微信支付,我在这就不说怎么去申请和开通了,我是看了微信官方文档后,想看官方文档的朋友可以到下面这个链接

class WxRedPack
{
    //配置参数信息
    const SHANGHUHAO = "***********";//商户号
    const PARTNERKEY = "***********";

    //核心支付函数,参数：请求地址和参数
    function pay($url, $obj)
    {
        $obj['nonce_str'] = $this->create_noncestr();    //创建随机字符串
        $stringA = $this->create_qianming($obj, false);    //创建签名
        $stringSignTemp = $stringA . "&key=2470f691aee2bfae92087c10e81cb4d0";    //签名后加api
        $sign = strtoupper(md5($stringSignTemp));    //签名加密并大写
        $obj['sign'] = $sign;    //将签名传入数组
        $postXml = $this->arrayToXml($obj);    //将参数转为xml格式
        $responseXml = $this->curl_post_ssl($url, $postXml);    //提交请求
        return $responseXml;
    }

    //生成签名,参数：生成签名的参数和是否编码
    function create_qianming($arr, $urlencode)
    {
        $buff = "";
        ksort($arr); //对传进来的数组参数里面的内容按照字母顺序排序，a在前面，z在最后（字典序）
        foreach ($arr as $k => $v) {
            if (null != $v && "null" != $v && "sign" != $k) {    //签名不要转码
                if ($urlencode) {
                    $v = urlencode($v);
                }
                $buff .= $k . "=" . $v . "&";
            }
        }
        if (strlen($buff) > 0) {
            $reqPar = substr($buff, 0, strlen($buff) - 1); //去掉末尾符号“&”
        }
        return $reqPar;
    }

    //生成随机字符串，默认32位
    function create_noncestr($length = 32)
    {
        //创建随机字符
        $chars = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789";
        $str = "";
        for ($i = 0; $i < $length; $i++) {
            $str .= substr($chars, mt_rand(0, strlen($chars) - 1), 1);
        }
        return $str;
    }

    //数组转xml
    function arrayToXml($arr)
    {
        $xml = "<xml>";
        foreach ($arr as $key => $val) {
            if (is_numeric($val)) {
                $xml .= "<" . $key . ">" . $val . "</" . $key . ">";
            } else {
                $xml .= "<" . $key . "><![CDATA[" . $val . "]]></" . $key . ">";
            }
        }
        $xml .= "</xml>";
        return $xml;
    }

    //post请求网站，需要证书
    function curl_post_ssl($url, $vars, $second = 30, $aHeader = array())
    {
        $ch = curl_init();
        //超时时间
        curl_setopt($ch, CURLOPT_TIMEOUT, $second);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        //这里设置代理，如果有的话
        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
        //cert 与 key 分别属于两个.pem文件
        //请确保您的libcurl版本是否支持双向认证，版本高于7.20.1
        curl_setopt($ch, CURLOPT_SSLCERT, dirname(__FILE__) . DIRECTORY_SEPARATOR .
            'cert' . DIRECTORY_SEPARATOR . 'apiclient_cert.pem');
        curl_setopt($ch, CURLOPT_SSLKEY, dirname(__FILE__) . DIRECTORY_SEPARATOR .
            'cert' . DIRECTORY_SEPARATOR . 'apiclient_key.pem');
        curl_setopt($ch, CURLOPT_CAINFO, dirname(__FILE__) . DIRECTORY_SEPARATOR .
            'cert' . DIRECTORY_SEPARATOR . 'rootca.pem');
        if (count($aHeader) >= 1) {
            curl_setopt($ch, CURLOPT_HTTPHEADER, $aHeader);
        }
        curl_setopt($ch, CURLOPT_POST, 1);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $vars);
        $data = curl_exec($ch);
        if ($data) {
            curl_close($ch);
            return $data;

        } else {
            $error = curl_errno($ch);
            echo "call faild, errorCode:$errorn";
            curl_close($ch);
            return false;
        }
    }

}

然后调用:

public function setredpack($moneys,$openid)
    {
        $money = $moneys; //最低1元，单位分
        $sender = "******";
        $obj2 = array();
        $obj2['wxappid'] = "**********"; //appid
        $obj2['mch_id'] = "***********";        //商户id
        $obj2['mch_billno'] = "********" . date('YmdHis') . rand(1000, 9999);//商户订单号
        $obj2['client_ip'] = $_SERVER['REMOTE_ADDR'];
        $obj2['re_openid'] = $openid; //接收红包openid
        $obj2['total_amount'] = $money;
        $obj2['min_value'] = $money;
        $obj2['max_value'] = $money;
        $obj2['total_num'] = 1;
        $obj2['scene_id'] = 'PRODUCT_2';
        $obj2['nick_name'] = $sender;
        $obj2['send_name'] = $sender;
        $obj2['wishing'] = "恭喜发财";
        $obj2['act_name'] = $sender ;
        $obj2['remark'] = $sender ;

        $url = "https://api.mch.weixin.qq.com/mmpaymkttransfers/sendredpack";

  $Wxpay = new WxRedPack();
        $res = $wxpay->pay($url, $obj2);return  $res;    }
