Answer 1

Answer 2

It's important to understand that PHP generate HTML and send it to your website, so depending on your question, you can't.
If you add an example here and are more precise/clear with your question, I can go in depth.
Enjoy :)

Answer 3

Yes you can.
I wrote an PHP script that just runs on CLI and echoes informative text to console that is served in no webserver.
I just need PHP and it's extensions for script execution so, no HTML is generated.

PHP website stands "popular general-purpose scripting language that is especially suited to web development" so is not "exclusive for web development".
