To test the validity of outputs, execute test.php by running:
  php test.php

You will notice that dictionaries may be a bit awkward. Python does not keep dictionaries in the same order in which 
they were added where as PHP does. PHP also only allows integers and strings as dicionary keys. Decimals, booleans, and 
nulls are automatically converted to their integer equivalent and everything else throws a fatal error.
