PHP intdiv(): integer quotient of a division

Get an integer quotient with intdiv()

intdiv() performs integer division and returns the integer quotient. The divisor must not be zero.

$quotient = intdiv(17, 5);
echo $quotient; // 3

Unlike the / operator, intdiv() returns an integer quotient truncated toward zero.

<?Php
echo intdiv(4,9); // Output 0
echo "<br>";
echo intdiv(3,5); // Output 0
echo "<br>";
echo intdiv(20,10); // Output is 2
echo "<br>";
echo intdiv(2,13); // Output is 0
echo "<br>";
echo intdiv(4,100); // Output is 0
echo "<br>";
echo intdiv(100,4); // Output is 25
?>

Syntax

int intdiv(int $dividend, int $divisor)

Parameter	DESCRIPTION
$dividend	Required : dividend of the division.
$divisor	Required: divisor of the division.

The output is integer quotient of the division.

Available since PHP 7.0 and supported in current PHP versions.

Example: Handling Division by Zero

try {
    echo intdiv(10, 0);  // Will throw DivisionByZeroError
} catch (DivisionByZeroError $e) {
    echo "Cannot divide by zero!";
}

Integer-range edge case: on a platform where PHP_INT_MIN / -1 cannot fit in an integer, intdiv(PHP_INT_MIN, -1) throws ArithmeticError.

Example: Dividing Negative Numbers

echo intdiv(-10, 3);  // Output: -3

Example: Dividing Large Numbers

echo intdiv(1000000, 500);  // Output: 2000

Example: Using intdiv() with Mixed Positive and Negative Numbers

echo intdiv(15, -4);  // Output: -3

Example: Dividing Evenly Divisible Numbers

echo intdiv(20, 5);  // Output: 4

These examples show how `intdiv()` handles large numbers, mixed positive/negative values, and evenly divisible integers.
Math Functions fmod(): floating point remainder (modulo) of the division
base_convert(): Convert number From any base to other
