How Does PHP Work?

PHP works by running code on a web server to create dynamic web pages. When a user visits a website with PHP, their browser sends a request to the server. The server processes the PHP code, which can include calculations, database queries, or generating content. Once the code is executed, the server sends the result as plain HTML back to the user’s browser, which displays the web page. This process happens quickly and invisibly to the user. PHP makes websites interactive by handling tasks like submitting forms, retrieving data, and updating content without needing the user to refresh the page.
