最有效的方法来计算PHP中的百分比

Question

i have a database with the current tax value (it is given in percentages to add like 41, 51 etc lets say it is 41 $tax = 41) The tax comes from the database the price is a post variable.

What i want to do is calcutate the new price when the tax is added. Currently i have.

$price = 120;
$tax = 41;
$total = (($price *100 + $price * $percentage)/100);

Is there any way to make it easyer? like:

$total = $price * 1.$tax

i know the last one wont work but its just what i had in mind.

What is the best solution?

您可以在查询数据库或查询时计算百分比

$total = $price * (1 + $tax/100);
