Common-ish - PHP is full of extensions that do strange things. I agree
that it shouldn't be fatal, but rather a warning (so it can be @-ed
out of existence in PHP's weird world). I note that
DocNotFoundException isn't mentioned in the bindings, however - we're
getting default behaviour, so it may be something that needs playing
with in SWIG. (Or is there a SWIG non-fatal equivalent of
SWIG_exception?)

I can't see why PHP5 shouldn't get this right, though. I'd expect
SWIG_exception to throw a PHP5 exception, although perhaps that needs
work in SWIG to do the right thing.
