Guys, look back at the advisory.  Apps written by *GOOD* PHP coders who 
*ARE* aware of security issues were prone to register_globals=on attacks.

As the guy said in the advisory, it's arguable whether it's the language's 
responsibility to guide you to write a secure app, or whether it's the 
coder's responsibility.  He says, and I agree with him, that if the 
language 'encourages' you to write insecure apps, by providing and 
streamlining insecure ways of implementing functionality, the language is 
at fault.  If most of the PHP apps out there are or were vulnerable to 
register_globals=on attacks, we can't (shouldn't) blame the whole world, 
but fix the language instead.
