Does a amfphp method 'have' to return something?

[guiltfilter]

Guys I have a amfphp gateway file with a method in it that doesnt return anything to flash, it works fine but I am wondering do I have to return something?

no.
And its also confusing in the docs how to write a function that takes no parameters either.
So much attention is paid to how you pass data and objects.
