Specifying a PHP Executable Path

I have a Macintosh with multiple versions of PHP. There is the default Mac version in `/usr/bin/php` as well as a number of alternative versions in various Web Server packages such as XAMPP and MAMP (which in turn has a large number of versions).

I teach PHP and I would like to try some code in alternative versions. I would also like to help students in setting up Atom Script in their development environment.

I have found that by setting an absolute path for `command` in `php.coffee`, it does the job. That’s not too hard.

The question is:

- is this the only way to specify the preferred path?
- is there the possibility of a gui for this?
