What are the recommended alternatives to framesets for integrating PHP scripts into HTML pages for improved usability and compatibility?

Framesets are not recommended for integrating PHP scripts into HTML pages due to compatibility issues with modern browsers and search engine optimization. Instead, a better approach is to use server-side includes or PHP includes to seamlessly integrate PHP scripts into HTML pages. This method allows for improved usability and compatibility while maintaining clean and organized code.
