What are some alternative methods to using frames in PHP for website development?

Using frames in PHP for website development can lead to issues with SEO, accessibility, and overall website performance. Instead of using frames, consider using PHP include or require functions to include reusable code snippets or templates into your web pages. This allows for better organization of code, easier maintenance, and improved performance.

<?php
// Include header file
include 'header.php';

// Main content of the page
echo '<div>This is the main content of the page.</div>';

// Include footer file
include 'footer.php';
?>
