How can the use of PHP tags [php] instead of code tags improve the presentation and readability of code within a forum post?

Using PHP tags instead of code tags can improve the presentation and readability of code within a forum post by highlighting the PHP code in a different color or style, making it easier for readers to distinguish between regular text and code. It also helps to properly format and display the PHP code, making it more visually appealing and easier to understand.

<?php
echo "Hello, World!";
?>
