[PHP] accessing $GLOBALS values

[Dennis Gearon]

I am looking at the 'tackle' library available at sourceforge. It's a 
'Tiny ACL' (access control list). Seems pretty good, simple and to the 
point.

   AND, it is database neutral, using ADODB. I haven't figured out how 
it does referential integrity in the database yet, but I suspect it's 
using table locking.

One thing I'm a little confused about is the usage of $GLOBALS array, in 
this manner:

  $GLOBALS[SOME_NAME].

I thought that it should be:

  $GLOBALS['SOME_NAME'].
