What is the purpose of using Modulo in PHP calculations?

When performing calculations in PHP, sometimes we need to find the remainder of a division operation. This is where the modulo operator (%) comes in handy. It returns the remainder of a division operation, which can be useful in various scenarios such as determining if a number is even or odd, cycling through a set of values, or checking for divisibility. 

// Using Modulo operator to check if a number is even or odd
$num = 10;

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