Under the heading "php - file upload: uploader.php" there are these sentences:-
----$_FILES['uploadedfile']['name'] - name contains the original path of the user uploaded file. ----$_FILES['uploadedfile']['tmp_name'] - tmp_name contains the path to the temporary file that resides on the server. The file should exist on the server in a temporary directory with a temporary name.
I don't understand these two sentences. Could someone explain?
