Protected Super Global Array

Hello, I'm not sure this was right place to ask this. Is there any possibility to add this kind of ability to php core. I want to create my suber global array with protection option option. Someting like that. new_super_global('myGlobal','mySignature') reading data from this super global was simple like $GLOBALS and updating this global someting like. update_super_global('myGlobal',mySignature,keyName,data) Yes of course we can use $GLOBALS. Everyone says it was not good idea because someting else. There where some windows registry thingy implementation's. Last time I was try to use Zend_Registry. Yep it works. and in every function I have to call it. And tell me where is the benefit. Regards Sancar
