You are understanding it correctly, the only thing that's missing
is the population. The variables are defined (set), but not all are
populated. $GLOBALS is a superglobal, you're right; globals set from
userland scripts are not superglobals, but do wind up in the $GLOBALS
array. Thus, all superglobals are globals, but not all globals are
superglobals.
