How can PHP be integrated with anchored URLs to maintain the user's position on a webpage after form submission?

When a form is submitted on a webpage, the page typically reloads at the top, causing the user to lose their position on the page. To maintain the user's position after form submission, you can integrate PHP with anchored URLs. This involves adding an anchor tag to the form action URL and using JavaScript to scroll to that anchor after the form is submitted. 

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    // Process form data
    
    // Redirect to the same page with an anchor tag
    header("Location: ".$_SERVER['PHP_SELF']."#formAnchor");
    exit();
}
?>

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

    <script>
        // Scroll to the anchor after form submission
        document.addEventListener("DOMContentLoaded", function() {
            if (window.location.hash === "#formAnchor") {
                document.getElementById("formAnchor").scrollIntoView();
            }
        });
    </script>

    <div id="formAnchor"></div>
</body>
</html>
