说到微信发红包,相信大家无人不知无人不晓,但是在编程PHP中要实现这个功能,具体代码大家知道吗?别着急,下面就让爱站技术频道小编带大家进入下文学习php实现微信发红包的方法!

具体如下:

具体代码:

然后实例化class.

   $toOpenId = 'asdasdasd'; //接收红包的用户的微信OpenId
    $hb = new WXHongBao();

    $hb->newhb($toOpenId,1000); //新建一个10元的红包,第二参数单位是 分,注意取值范围 1-200元
    //以下若干项可选操作,不指定则使用class脚本顶部的预设值
     $hb->setNickName("土豪有限公司");
     $hb->setSendName("土豪");
     $hb->setWishing("恭喜发财");
     $hb->setActName("发钱活动");
     $hb->setRemark("任性一把");

    //发送红包

    if(!$hb->send()){ //发送错误

      echo $hb->err();

    }else{

      echo "红包发送成功";

    }
