What are the potential challenges of running a PHP script automatically on an IIS Server?

One potential challenge of running a PHP script automatically on an IIS Server is ensuring that the server is properly configured to handle PHP files. This may involve installing PHP on the server, setting up the necessary handlers in IIS, and configuring the PHP engine to work with IIS. Additionally, permissions and security settings must be properly configured to prevent unauthorized access to the PHP files.
