Why is it important to include the http:// or https:// protocol in PHP href links?

Including the http:// or https:// protocol in PHP href links is important because it specifies the protocol that should be used to access the linked resource. Without it, the browser may default to a different protocol, potentially leading to broken links or security issues. To ensure that the links work correctly and securely, always include the appropriate protocol in href attributes.
