Hi,
The setting of register globals will not affect the $_PHPA global.
Register globals causes the elements such as those in GET and POST form
requests, and server variables to be registered as globals, *in
addition* to being available via their respective global arrays. So,
for example, $_SERVER['SCRIPT_FILENAME'] would also be accessible as
the global variable $SCRIPT_FILENAME. Setting register globals to off
prevents that behaviour.
It's a convenience feature, but can also be a problem because of the
arbitrary variables that can be assigned, and in particular, a risk
because a malicious user could submit a form with arbitrarily named
elements that may cause code to malfunction.
However, $_PHPA is registered as a global variable by PHPA, and is
still available as the global $_PHPA or $GLOBALS['_PHPA']
Thanks for the post though!
