(unless you have a really > cool useful idea ;-) So it sounds like it is possible. I have been reading the php source that I think deals with superglobals. I have two ways I would like to use superglobals. One way would be to provide application variables that are accessible from multiple sessions. But that is not what I think the coolest idea is. The other, more important way I would like to implement a superglobal is to implement "aspects" in the framework I am working on (http://sourceforge.net/ projects/cep). While the $_ASPECT super global will not have any value be default, it will be a place to store object references that could be considered "aspects" in AOP languages. These aspects would be things like Logging, DB, Authentication, Cacheing, etc. $_ASPECT['db'] = new DB::connect(); $_ASPECT['log'] = new Log::singleton(); $_ASPECT['auth'] = new Auth(); This provides a cleaner alternative to storing these global object references inside an array inside the $GLOBALS array. There may be a better way to implement aspects in PECL, but this is all I got so far.
