Ok, i've tried all i could, from 3.0.10 to 3.0.17 and it's doing the same on every of these.

I have a file called test.php3 in the root of my web.
I use the CGI version of PHP.

http://myserver/test.php3/test?hello=1

returns this info:

PHP_SELF /test.php3/test.php3/test 
REQUEST_URI 
SCRIPT_NAME /test.php3 
PATH_INFO /test.php3/test 
HTTP_GET_VARS Array 
QUERY_STRING value=1 

if i put the file in a subfolder:
http://myserver/member/test.php3/test?hello=1

i get this:

PHP_SELF /member/test.php3/member/test.php3/test 
REQUEST_URI 
SCRIPT_NAME /member/test.php3 
PATH_INFO /member/test.php3/test 
HTTP_GET_VARS Array 
QUERY_STRING value=1
