Are there best practices for handling 404 errors in PHP to maintain transparency with the client?

When handling 404 errors in PHP, it's important to maintain transparency with the client by providing a clear and informative error message. One common best practice is to create a custom 404 error page that includes a friendly message and possibly suggestions for the user to navigate back to the correct page.

<?php
header("HTTP/1.0 404 Not Found");
echo "<h1>404 Not Found</h1>";
echo "<p>The page you are looking for could not be found. Please check the URL or navigate back to the homepage.</p>";
