上面的代碼太多了吧

//你的問題要用switch語句，還沒學(xué)，代碼和圖示如下：
<?php
header("Content-type:?text/html;?charset=utf-8");
????date_default_timezone_set('Asia/ShangHai');
????$today?=?date('m-d',time());//獲取當(dāng)天日期
????$birthday?=?"02-14";//生日
????$money=2000;
????$discount;
????switch($money){
????case($money>=1500):?//滿1500以上的75折
????????$discount=0.75;
????????break;
????case($today==$birthday):??//今天生日8折
????????$discount=0.8;
????????break;
????case($money>=500):??//滿500不滿1500的95折
????????$discount=0.95;
????????break;
????default:
????????$discount=1;
????????break;
????}
????$money=$money*$discount;
?
????echo?$money;
?>
