Note, this is only the default value for the fully 
configurable PHP directive register_globals.  Please 

Also, note that global and register_globals are different 
topics all together.  And that the track_vars directive 
hasn't been useful since PHP 4.0.2.  It's always on now.

Using superglobals is not secure, but it can be nice to know 
where your data is coming from so if you expect a cookie 
variable, a get variable won't take its place.  Like if you 
have a cookie named 'foo', with register_globals one might 
use $foo, but if the cookie does not exist a user could 
pass a get variable $foo through the url ... Just a simple 
example :)

The following post might help clear things up regarding 
superglobals, variable scope, and register_globals:
