What steps should be taken to ensure PHP files are properly executed on a server?

To ensure PHP files are properly executed on a server, you need to make sure that the server is configured to recognize and process PHP files. This can be done by installing PHP on the server and configuring the web server (such as Apache or Nginx) to handle PHP requests. Additionally, setting the correct file permissions and ensuring the PHP code is error-free will help in proper execution.
