Okay so a variable would be dynamic - I understand - I didn't write the
code, I just copied and pasted it. The 'dynamic variable' comment was there
from before. And I accept that to answer the question I could have
constructed another procedure to test if PHP5 did/did_not support the
construct. So I guess I asked the wrong question then - sorry about that
:¬)

What I really need some with was understanding why $categoryvalue would
be empty.
