How to cap a PHP int value

Question

I am making some calculations with PHP and I don't want a number to be above 100. So, for example I want 50 + 80 to be 100 and not 130. Basically cap any result to 100. How can I achieve this?

Answer 1

You could use min:

min($sum, 100)

This returns either $sum if $sum < 100 or 100 otherwise.

Answer 2

You can just use the min function:

$result = min($result, 100);
