How can PHP tags be properly used to ensure code readability and functionality in a forum thread?

To ensure code readability and functionality in a forum thread when using PHP tags, it is important to properly format the code within the tags. This includes using indentation, comments, and clear variable names to make the code easy to understand for other users. Additionally, it is crucial to ensure that the PHP code is error-free and functions as intended.

<?php

// Example PHP code snippet with proper formatting for a forum thread
$variable1 = 5;
$variable2 = 10;

$result = $variable1 + $variable2;

echo "The result is: " . $result;

?>
