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";
