Boneheaded PHP math question

Last Modified: 2015-03-25
Let's say you wanted to figure out how many cars a group needs to rent.

$capacity is the number of people the car can hold
$people is the number of people in your group

My first thought on how to approach it would be to do something like

while ($people > 0) {
$cars ++;
$people = $people - $capacity;

That way it just kinda iterates up the number of cars as groups.  Say car capacity is 5... If there's one person, it only occurs once.  If there's 6 people, it cycles twice, 2 cars...etc.

Is there a better way you think of approaching that?  Just feels kinda sloppy to me doing it that way.
