Division¶

Division is the mathematical division. It applies to numbers: integers and float.

It also works with booleans and null, which are converted to integers. Other types are not allowed for division and yield a fatal error.

Division may be resulting in an integer or a float, whatever the type of the initial operands. PHP produces integers whenever possible.

Division by zero, or by any value that is cast to 0, leads to a DivisionByZeroError.

The operator for division is the slash /. The backslash \ is used for namespaces.

There is a function for the integer division: intdiv(); and % for the modulo operator, aka the remaining.

<?php

$a = 10 / 2.5; // 4.0

?>
