NYCPHP Meetup

[Chris Bielanski]

I'll toss in a guess - but it's complete speculation:

With register_globals turned on, the values all get put in a single massive
symbol table (or heap, or whatever) and all values are references. With it
turned off, the symbol table can be managed more effectively, and you get
values in place of those references.

Of course, I could be way off - I can envision what's going on but my lack
of scholastic training in the subject serves to limit my vocabulary.
