Are there any best practices for handling page reloads in PHP when using frames?

When handling page reloads in PHP with frames, it's important to ensure that the content within the frames is not lost upon reloading the page. One way to achieve this is by using session variables to store the frame content and then retrieving it on page reloads. This ensures that the frame content remains intact even after the page is reloaded. 

<?php
session_start();

// Check if frame content is set in session
if(isset($_SESSION['frame_content'])) {
    $frame_content = $_SESSION['frame_content'];
} else {
    $frame_content = ''; // Default frame content
}

// Update frame content based on user input
if(isset($_POST['frame_input'])) {
    $frame_content = $_POST['frame_input'];
    $_SESSION['frame_content'] = $frame_content; // Store frame content in session
}
?>

<!DOCTYPE html>
<html>
<head>
    <title>Page with Frames</title>
</head>
<body>
    <frame>
        <!-- Display frame content -->
        <form method="post">
            <input type="text" name="frame_input" value="<?php echo $frame_content; ?>">
            <input type="submit" value="Save">
        </form>
    </frame>
</body>
</html>
