How do I specify a default null object, or otherwise make the argument argument optional?

To my knowledge: can't be done. But you can check any args through the func_get_arg*() functions, then per-parameter push 'm through a check function that checks if their primary properties are set. It's equivalent to checking for null ( / bad) objects.

Thank you to everybody. I think I will see how far I can get with func_get_arg - it may solve the problem. The other hackish solution I thought of is to put the object arguments into a key/value array and pass the array as a single argument to the function. That way I can check for the key and if the key is set, grab the object associated with it.
