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.

Regards

SG(rfc1867_uploaded_files) will have a list of filenames uploaded.

It stores them in the globals hash table.  Take a look at 
php_session_start() in ext/session/session.c, and look for "_COOKIE", for 
an example of how you can access these.  Once you have a reference to the 
$_FILES hash, you can iterate it to get each file (which is also a hash), 
and then lookup each element to obtain its value.
