What is the significance of the modulo operator in PHP in relation to this issue?

The issue is that we need to check if a number is even or odd in PHP. One way to do this is by using the modulo operator (%), which returns the remainder of a division operation. If a number modulo 2 equals 0, then it is even; otherwise, it is odd. 

$number = 10;

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