Answer 1

Just a short list of what PHP is capable of:
- Generating dynamic page content
- Creating, opening, reading, writing, deleting, and closing files on the server
- Collecting form data
- Adding, deleting, and modifying information stored in your database
- controlling user-access
- encrypting data
- and much more!

- Sololearn (PHP course)

As you can see there is no special use of PHP if you don't use anykind of database i.e. store information given from user . If you want to make a website that just gives information , not any thing related to database , then there aren't many reasons to use PHP
For a simple website HTML , CSS , and JS are enough

Answer 2

If you won't be using any kind of login and comments in your website , then this much is enough . Buy a domain name for your website or use a free one to launch it .
000webhost is popular for free hosting try it .
