What alternative approaches can be recommended for PHP developers who need to use frames but want to avoid their limitations, as discussed in the forum thread?

The issue with using frames in PHP is that they have limitations such as SEO problems and accessibility issues. One alternative approach for PHP developers is to use iframes instead. Iframes allow you to embed another HTML document within your current document, providing similar functionality to frames without the same limitations.

<!DOCTYPE html>
<html>
<head>
    <title>Using Iframes in PHP</title>
</head>
<body>
    <h1>Main Content</h1>
    <iframe src="content.php" width="100%" height="500px"></iframe>
</body>
</html>
