Check the release notes or changelogs..
I believe there was a notable change in 4.0.5 regarding 'referencing'
you may have to deal with,
and 'reference counting' was added later on but this should have little
affect on backwards compatibility.
Also, the input mechanism has changed, although you could get the old
behaviour back by changing
the php.ini , it is recommended for a number of reasons to 'upgrade'
your source to ensure it will continue
to work in future versions of PHP. See: http://www.php.net/release_4_1_0.php
