Good point. I answered a question on Stack Overflow about PHP's $_POST
variable; variables like this are called superglobals in the PHP
documentation. The poster said that "superglobal" should mean that the
value is shared by all scripts, because his intuitive interpretation of
the term means that its scope should be wider than an ordinary global
variable. Never mind that this is not actually a common computer term,
the PHP designers coined it themselves to refer to their particular use
(these variables are "super" because they're automatically visible in
functions and methods, you don't have to use the "global" declaration).
