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));
var_dump(intdiv(PHP_INT_MIN, -1));
var_dump(intdiv(1, 0));
?>
