intdiv — Integer division

### Description

int intdiv ( int `$dividend` , int `$divisor` )

Returns the integer quotient of the division of `dividend` by `divisor`.

### Parameters

`dividend`

  Number to be divided.

`divisor`

  Number which divides the `dividend`.

### Return Values

The integer quotient of the division of `dividend` by `divisor`.

### Errors/Exceptions

If `divisor` is 0, a DivisionByZeroError exception is thrown. If the `dividend` is `PHP_INT_MIN` and the `divisor` 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));
var_dump(intdiv(PHP_INT_MIN, -1));
var_dump(intdiv(1, 0));
?>`

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