What are the potential risks and drawbacks of including URLs in PHP files using require or include statements?

Including URLs in PHP files using require or include statements can pose security risks, as it allows for remote code execution and opens up the possibility of including malicious content. To mitigate this risk, it is recommended to only include local files using relative paths within the same server environment.
