Forget it. Obviously you haven't understood what interfaces in PHP are
used for and what you can do/ensure with them. Just an example: Without
these interfaces it wouldn't be possible to use 'foreach' to iterate
over any arbitrary object:

foreach ($directory as $file) {...}
foreach ($resultSet as $record) {...}
