如何在PHP中找到X的X％的答案? [英] How would I find the answer to X% of X in PHP?

问题描述

我有两个变量:

$percent = '3.5'; //this is the percentage
$order = 400;
//so how would i get $percent of $order?

现在在PHP中如何找出400的3.5％(我知道它的14)-但想知道如何使用上述两个变量直接在PHP中计算出它.

Now in PHP how would I find out what 3.5% of 400 is (I know its 14) - but would like to know how to calculate it directly in PHP using those two variables above.

感谢您的回应.

推荐答案

百分比"仅表示每100"或超过100"或"/100"

"Percent" just means "per 100" or "over 100" or "/ 100"

$percentOfOrder = $order * ($percent / 100);
