php round to the next whole number

Question

In PHP, I need to round off a number to the next whole number. For example, in my program, I am using the round as below.

$val = round(count($names)/15);

If count($names) is 1.2, I need it to be rounded off to 2 instead of 1. I tried to do the below approach.

  $val = round(count($names)/15) + 1;

However, in the above approach, if I have count($names) as 1.6, It is getting rounded off to 3 as I increment it by 1.

Is there a way where no matter what the decimal value is, it needs to be rounded off to the next whole number?

Answer 1

How about using ceil()

Then your code becomes:

$val = ceil(count($names)/15);
