What is the purpose of creating a custom error 404 page in PHP?

Creating a custom error 404 page in PHP allows you to provide a more user-friendly and visually appealing error message to visitors when they encounter a page not found on your website. This can help improve the overall user experience and provide guidance on what steps to take next. Additionally, a custom error page can also help retain visitors on your site by offering them alternative links or resources to explore. 

<?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 go back to the homepage.</p>";
// Add additional content or links here
?>
