    Description

    intdiv(int $num1, int $num2): int

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