Question

In languages like C or Python 2, if I divide an integer by an integer, I get an integer:

>>> 8/3
2

But in PHP, if I divide an integer by another integer with /, sometimes I get a float:

php > var_dump(6/3);
int(2)
php > var_dump(8/3);
float(2.6666666666667)

I’d like to do division like in Python or C, so that 8/3 is 2. How can I do that in PHP?

Answer 1

As of PHP 7, we can use the intdiv built-in function to get an integer value:

intdiv(8,3); // 2

For earlier versions of PHP, we can use the round() function to get an integer rounded value:

round(8 / 3); // 3

Or we can use the floor() function to get an integer value:

floor(8 / 3); // 2
