What are the potential issues with using the font tag in PHP for formatting output?

Using the font tag in PHP for formatting output is not recommended as it is an outdated and deprecated method. It is better to use CSS for styling and formatting text in PHP output. This will ensure better separation of content and presentation, making the code cleaner and more maintainable.

// Instead of using the font tag, use CSS for styling text in PHP output
echo '<p style="font-family: Arial; font-size: 14px; color: #333;">Hello, World!</p>';
