How can PHP be effectively used in web development to create dynamic content?

PHP can be effectively used in web development to create dynamic content by embedding PHP code within HTML files. This allows for the execution of PHP scripts on the server-side to generate dynamic content based on user input or database queries. By using PHP, developers can easily create interactive websites with dynamic features such as user authentication, form processing, and content management.
