Answer 3

PHP provides a connection to database and interface to store and retrieve data from it, also PHP can generate parts or whole pages for website depending of that data. Example is this Sololearn forum - it has not static pages with topics and answers, all this pages are generated by site engine working on PHP or similar technology that reads corresponding data stored in database and then shows it to user in a way you can see.
