In a dynamic site, the process is different, the HTML file does not yet exist. It will be generated according to the parameters that you will send to it.

You will send them either consciously, for example by filling out a form and clicking on send. For example, in a quote request form, you will give the number of products desired, and the type of product desired and then the server will receive these parameters and will process the request.
You can also do it unconsciously, i.e. by clicking on a link. This link has parameters that are put in the URL (as we saw earlier in the part on URLs, it will be a URL of the form mon-site.com.
the script was made to understand these parameters, obviously, we do not send any parameters to any script, and according to these parameters, it will create an HTML file.

So it goes like this, you send a request with parameters, consciously or unconsciously, and the server understands these parameters, generates an HTML file, and then sends it back to you. It is displayed on your screen.

So as I explained to you, for a dynamic site to exist, we need a language called “server language”. And the server language par excellence, the most used in the world, is the PHP language.
