After upgrading from 4.1.2 to 4.2.2 the behaviour of the returned $userfile has changed.

4.1.2 returned "NONE" on a file not being present, and 4.2.2 returns a null value.

We have register_globals set to on, none of the remaining configuration has changed. After reverting to php 4.1.2 the problem disappears.

Other config info:

Kernel 2.4.18
apache versions 1.3.20 (our test servers )and 1.3.26 (our production servers.

configuration string:

'./configure' '--with-apxs=/usr/local/apache/bin/apxs' '--with-xml' '--enable-bcmath' '--enable-calendar' '--enable-ftp' '--with-gd=../gd-1.8.4' '--with-jpeg-dir=/usr/local' '--with-png-dir=/usr' '--with-imap=../imap-2001.BETA.SNAP-0105220031' '--with-mcrypt' '--with-ming=../ming-0.1.1' '--with-mysql' '--with-pear' '--enable-track-vars' '--with-ttf' '--enable-versioning' '--with-zlib'

Another php coders post on the same issue:

The above link includes plenty of examples between different versions of php.

This is not any bug. The uploading code changed a lot in 4.2.0..that's one reason why there is 4.2.0 and not 4.1.3..

Hint: Use the error field, codes defined here:

I realise you've change the scheme, but is it wise having no backwards compatiblity?

I would have thought having the ability to support the old method would have been important, else it's going to break vast number of scripts.
