How can PHP developers ensure that the "Weiter in 5 Sekunden..." feature is user-friendly and compliant with web standards?

To ensure that the "Weiter in 5 Sekunden..." feature is user-friendly and compliant with web standards, PHP developers can use JavaScript to implement a countdown timer that redirects the user after 5 seconds. This will provide a clear indication to the user of when the redirect will occur and ensure a smooth user experience.

<!DOCTYPE html>
<html>
<head>
    <title>Redirect in 5 Seconds</title>
    <script>
        setTimeout(function() {
            window.location.href = 'https://example.com';
        }, 5000);
    </script>
</head>
<body>
    <h1>Redirecting in 5 seconds...</h1>
</body>
