PHP auto global variables inside C extension

Hi everyone, I was wondering if there was any way in which the PHP auto global variables could be used inside the C extension code? Where does php store all the global variables? Well what I am trying to do is put the uploaded file in a custom database. But for that I require all the four paramaters, viz |$_FILES['userfile']['name'], ||$_FILES['userfile']['type'], ||$_FILES['userfile']['size'] and| |$_FILES['userfile']['tmp_name']|. So, instead of the user having to pass all this from php as function arguments, is there no way i can get these directly? Inside the extension code? Thanking you in advance.
