[Tutorial] How to find if a number is odd or even

Hi there!

In this tutorial I'll write some basic PHP code on how to find if a number is odd or even.

The idea behind the code is that even numbers have zero reminder when divided by 2, while odd numbers have 1 as a reminder after division by 2. For this I'll use PHP modulus operator (%).

<?php
if ($number % 2 == 0)
{
    echo "even";
}
else
{
    echo "odd";
}
?>
