Re: [PHP] PHP globals aren't really globals

That's correct.  To be perfectly correct here, what you are doing is
creating a reference to the global variable.  Think of it as an alias to
the same variable as the global variable.

  global $foo;

would be equivalent to:

  $foo = & $GLOBALS['foo'];

With the latter giving you the ability to use a different name for the
local reference to the globally-scoped variable.
