折扣的公式是什么
in php is there any default function ,
在 php 中是否有任何默认功能,
this is my formula, chk it is correct way ,
这是我的公式,这是正确的方法,
$SELLING_PRICE = $ACTUAL_PRICE-$CHK_DISCOUNT_THERE;
$PRICE_AFTER_DISCOUNT = $ACTUAL_PRICE-$SELLING_PRICE;
回答by Darin Dimitrov
selling price = actual price - (actual price * (discount / 100))
So for example if (actual price) = $15, (discount) = 5%
例如,如果(实际价格)= 15 美元,(折扣)= 5%
selling price = 15 - (15 * (5 / 100)) = .25

Like Literally you can copy paste this formula:
就像字面意思一样,您可以复制粘贴此公式:
$total = $total - ($total * ($discount_amount/100));
