How can using code tags like [php]code[/php] improve the presentation of PHP code in online forums and discussions for better readability and understanding?

Using code tags like [php]code[/php] in online forums and discussions can improve the presentation of PHP code by formatting it in a distinct way that stands out from regular text. This helps to clearly differentiate code snippets from the surrounding text, making it easier for readers to identify and understand the code being presented. Additionally, code tags often provide syntax highlighting, which further enhances readability by color-coding different elements of the code.

<?php
// Example PHP code snippet using code tags
echo "Hello, World!";
?>
