How to use Modulo Operator in PHP ?

The modulo operator in PHP is represented by the percentage symbol %. It calculates the remainder of one number divided by another. The basic syntax for the modulo operator is-

Syntax:

$result = $num1 % $num2;

Here, $num1 is the dividend, and $num2 is the divisor. The result will be the remainder after dividing $num1 by $num2.

Example 1: This example describes the Basic Modulo Operation.

<?php

$dividend = 10;
$divisor = 3;

$result = $dividend % $divisor;

echo "Remainder is: $result";

?>

Remainder is: 1

Example 2: This example checks for Even or Odd Numbers.

<?php

$number = 7;

if ($number % 2 == 0) {
    echo "$number is an even number.";
} else {
    echo "$number is an odd number.";
}

?>

7 is an odd number.
