In what scenarios would using frames in PHP to separate database queries from visible content be a viable solution, and what are the drawbacks of this approach?

Using frames in PHP to separate database queries from visible content can be a viable solution when you want to keep your code organized and maintain separation of concerns. This approach can help improve code readability and maintainability by isolating database logic from the presentation layer. However, using frames may introduce complexity and make it harder to debug and maintain the code in the long run.

<!-- index.php -->
<html>
<head>
    <title>Using Frames in PHP</title>
</head>
<frameset cols="25%,75%">
    <frame src="queries.php">
    <frame src="content.php">
</frameset>
</html>

<!-- queries.php -->
<?php
// Database queries go here
?>

<!-- content.php -->
<?php
// Visible content goes here
?>
