It is global for the current invocation of the script (and all code
included from it). To make variables global between all
invocations/scripts in a given session, you need to use the session
management functions of PHP4. Look at the manual and search
phpbuilder.com for some intro on that.

If set to "on", PHP automatically generates global vars from values
passed via GET/POST requests and cookies. Example: calling
http://foo.bar/test.php?answer=42
will call test.php with a global variable $answer set to "42"
