Can PHP be used to change the properties of a webpage, such as window size and toolbar visibility?

PHP cannot directly change the properties of a webpage such as window size or toolbar visibility, as these are typically controlled by the client-side browser. However, PHP can generate dynamic content and interact with the server to provide different responses based on user input or other conditions. To change the properties of a webpage, you would typically use JavaScript or CSS on the client-side.
