This also means that the bitwise operators, error control operators and execution operators are not supported at this moment. But as said before, it supports a subset. Supporting the Error Control operator when there are no errors generated is a bit strange anyway.
It is fun to be able to evaluate thing, but it is even more fun to see things that are evaluated. So the tool produces evaluated output. This means that everything that is not within PHP-tags is outputted. There is also support for the 'echo' statement, so this produces output too. I have put a small test-file online here. The output of eval-php is available here, it can be compared with the real output of PHP itself here, take a look at the source of the page.
I think it is all pretty fancy :)
