Note Submitter: Anonymous ---- I sorely apologize if this point seems to be obvious, but being slightly impatient, I do not care to know how many times I overlooked this. For God's sake, notice the lack of the '$' in front of objects when referencing them with '$this'. Not included, this allows class variables to be properly addressed. eg, $this->$a, will NOT work properly with clone(), but this will: $this->a.
