说明

int intdiv ( int $dividend , int $divisor )

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

参数

dividend: Number to be divided.
divisor: Number which divides the dividend.

返回值

The integer quotient of the division of dividend by divisor.

错误／异常

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.

范例

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)
