sum that up for me

The types of PHP are just APIs for web servers to interface with PHP

The web server you use will most likely determine what type of PHP to use.

You should consider your needs before picking which version of PHP to use.

What about CLI?

CLI is command line SAPIyou know $ php…

$ php -a access interactive shell

$ php -r “echo ‘hi’”;

hi

$ php your_file.php
