PHP Manual: Integer division

Description

int intdiv(int $num1, int $num2)

Returns the integer quotient of the division of num1 by num2.

Parameters

num1: Number to be divided.
num2: Number which divides the num1.

Return Values

The integer quotient of the division of num1 by num2.

Errors/Exceptions

If num2 is 0, a DivisionByZeroError exception is thrown. If the num1 is PHP_INT_MIN and the num2 is -1, then an ArithmeticError exception is thrown.

Examples

Example #1 intdiv example

<?php
var_dump(intdiv(3, 2));
var_dump(intdiv(-3, 2));
var_dump(intdiv(3, -2));
var_dump(intdiv(-3, -2));
var_dump(intdiv(PHP_INT_MAX, PHP_INT_MAX));
var_dump(intdiv(PHP_INT_MIN, PHP_INT_MIN));
?>

The above example will output:

int(1)
int(-1)
int(-1)
int(1)
int(1)
int(1)

Example #2 intdiv Example With Invalid Divisor

<?php
try {
    intdiv(PHP_INT_MIN, -1);
} catch (Error $e) {
    echo get_class($e), ': ', $e->getMessage(), PHP_EOL;
}

try {
    intdiv(1, 0);
} catch (Error $e) {
    echo get_class($e), ': ', $e->getMessage(), PHP_EOL;
}
