So, how does PHP work?

The PHP program communicates with the site server, which is the software that distributes web pages to the rest of the world. When you type a URL into your web browser’s address bar, you’re instructing the webserver at that URL to send you an HTML file. The web server responds by sending the requested file. Your browser reads the HTML file and displays the web page. When you request a file from the webserver by pressing a source on a web page, you’re also requesting a file from the webserver. Additionally, when you click a button on a web page that submits a form, a file is processed by the webserver.

Step 1

User send page request to the webserver

Step 2

The server forwards that request to PHP

Step 3

PHP will send the request to the Database and respond back to the server.

Step 4

The request will be then sent back to the user’s device
