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"; }
