How can PHP be used to handle errors in form submissions and prevent the "Page no longer current" message in browsers like IE?

When a form is submitted in PHP and an error occurs, the browser may display a "Page no longer current" message, especially in Internet Explorer. To prevent this, you can use PHP to handle errors and redirect the user back to the form page with error messages displayed. This can be achieved by checking for form submission, validating input, and displaying errors if any. 

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Form submission handling
    // Validate input
    if (/* validation fails */) {
        $error = "Error message here";
    } else {
        // Process form data
        // Redirect to success page
        header("Location: success.php");
        exit();
    }
}
?>

<!DOCTYPE html>
<html>
<head>
    <title>Form Submission</title>
</head>
<body>
    <form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">
        <!-- Form fields here -->
        <input type="submit" value="Submit">
    </form>

    <?php if(isset($error)) { ?>
        <p><?php echo $error; ?></p>
    <?php } ?>
</body>
</html>
