I get following output with PHP4.0.4pl1 w/ Linux
(I set php.ini to store uploaded files info to $HTTP_UPLOAD_FILES.
You will get different output if you don't)
--------- OUTPUT - when files to upload are not specified ----------
Key = userfile, Val = Array
a.. Key = name, Val = Array
a.. Key = 0, Val =
a.. Key = 1, Val =
a.. Key = type, Val = Array
a.. Key = 0, Val = application/octet-stream
a.. Key = 1, Val = application/octet-stream
a.. Key = tmp_name, Val = Array
a.. Key = 0, Val = none
a.. Key = 1, Val = none
a.. Key = size, Val = Array
a.. Key = 0, Val = 0
a.. Key = 1, Val = 0

I cannot understand what you mean well....

See the code and output, it works. (at least when PHP stores uploaded file
info to $HTTP_UPLOAD_FILES. Does not work w/o it?)

Did you copy temp file? It will be deleted.
