How can the meta-refresh tag in PHP be used effectively in form submissions to maintain user experience and avoid white screen errors?

When a form is submitted in PHP, the page reloads and displays a white screen while processing the form data. To maintain user experience and avoid white screen errors, the meta-refresh tag can be used to automatically redirect the user to a different page after form submission. This ensures that the user sees a visually appealing message or a different page instead of a blank screen. 

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Process form data here
    
    // Redirect to a different page after form submission
    echo '<meta http-equiv="refresh" content="0;url=thankyou.php">';
    exit;
}
?>
<!DOCTYPE html>
<html>
<head>
    <title>Form Submission</title>
</head>
<body>
    <form method="post" action="<?php echo $_SERVER["PHP_SELF"]; ?>">
        <!-- Form fields go here -->
        <input type="submit" value="Submit">
    </form>
</body>
</html>
