What are the limitations of using PHP for real-time updates, such as displaying new tweets without refreshing the page?

PHP is a server-side language, meaning it runs on the server and generates the HTML that is sent to the client's browser. This makes it difficult to implement real-time updates, such as displaying new tweets without refreshing the page, as PHP scripts need to be executed on the server before any changes can be made to the page. To achieve real-time updates, you would typically need to use client-side technologies like JavaScript along with AJAX to fetch new data from the server and update the page dynamically.
