When troubleshooting cookie-related issues in PHP, you can use HTTP headers to inspect the cookies being set or retrieved by your application. By examining the headers, you can determine if the cookies are being properly set, retrieved, or if there are any conflicts with existing cookies. This can help pinpoint the source of the issue and guide you towards resolving it effectively.
