php - How do you execute a method in a class from the command line

Question

Basically I have a PHP class that that I want to test from the commandline and run a certain method. I am sure this is a basic question, but I am missing something from the docs. I know how to run a file, obviously php -f but not sure how to run that file which is a class and execute a given method

Answer 1

This will work:

php -r 'include "MyClass.php"; MyClass::foo();'

But I don't see any reasons do to that besides testing though.
