What role do code tags play in making PHP code more readable and accessible in online forums?

Using code tags in online forums helps to maintain the formatting and indentation of PHP code, making it more readable and accessible to other users. It also distinguishes the code from regular text, making it easier to identify and understand. To use code tags, simply wrap your PHP code in [code] [/code] tags when posting on forums. Example: [code] <?php echo "Hello, World!"; ?> [/code]
