What are the potential security risks of using the file:// protocol in PHP applications, especially in browsers like Chrome?

Using the file:// protocol in PHP applications can pose security risks, especially in browsers like Chrome, as it allows access to local files on the user's system. This can lead to potential data breaches or unauthorized access to sensitive information. To mitigate this risk, it is recommended to avoid using the file:// protocol and instead serve files through a web server.
