Even and Odd Numbers in PHP

In PHP, determining whether a number is even or odd is a fundamental operation. Even numbers are divisible by 2, while odd numbers are not. Here’s a simple example in PHP:

Key Concepts:

Even Numbers:

• Even numbers are divisible by 2 and typically end with digits like 0, 2, 4, 6, or 8 (e.g., 2, 4, 6, 8, 10).

Odd Numbers:

• Odd numbers are not divisible by 2 and often end with digits like 1, 3, 5, 7, or 9 (e.g., 1, 3, 5, 7, 9).

PHP Example:

<?php
$number = 789;

// Check if the number is even or odd.
if ($number % 2 == 0) {
    echo "$number is an Even Number.";
} else {
    echo "$number is an Odd Number.";
}
?>

Output:

The above PHP code will produce the following output:

This output indicates that the number 789 is classified as an odd number.
