What are the drawbacks of using frames in PHP web development?

One major drawback of using frames in PHP web development is that they can make the website less accessible and harder to navigate for users with disabilities or using assistive technologies. Additionally, frames can negatively impact search engine optimization (SEO) as search engines may have difficulty crawling and indexing the content within frames. To solve this issue, it is recommended to avoid using frames and instead utilize modern web development techniques like CSS for layout and JavaScript for dynamic content.

<!DOCTYPE html>
<html>
<head>
    <title>No Frames Example</title>
    <style>
        /* CSS for layout */
    </style>
</head>
<body>
    <header>
        <!-- Header content -->
    </header>
    <nav>
        <!-- Navigation content -->
    </nav>
    <main>
        <!-- Main content -->
    </main>
    <footer>
        <!-- Footer content -->
    </footer>
</body>
</html>
