(PHP 7, PHP 8)
intdiv — Integer division
Returns the integer quotient of the division of num1 by num2.
num1Number to be divided.
num2Number which divides the num1.
The integer quotient of the division of num1 by num2.
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.
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;
}
?>The above example will output:
ArithmeticError: Division of PHP_INT_MIN by -1 is not an integer DivisionByZeroError: Division by zero
