What are some common pitfalls to avoid when implementing URL redirection in PHP scripts?

One common pitfall to avoid when implementing URL redirection in PHP scripts is not using the proper HTTP status codes. It is important to use the correct status code (e.g., 301 for permanent redirection, 302 for temporary redirection) to ensure that search engines and browsers handle the redirection correctly. 

// Incorrect way to redirect without specifying the status code
header('Location: https://www.example.com/new-page.php');
exit;

// Correct way to redirect with the proper status code
header('HTTP/1.1 301 Moved Permanently');
header('Location: https://www.example.com/new-page.php');
exit;
