This sounds kind of dangerous, especially in combination with convert_to_string. Of course, when using ZPP it's probably fine since ZPP result will be checked, but when not I'm not sure what happens when conversion is initiated otherwise - i.e. what the result would be and what happens if the result is used since the code assumed if string conversion didn't bail it returned some useful string. I think this was the main reason we didn't allow exceptions in __toString() - it's hard to handle them properly. -- Stas Malyshev smalys...@gmail.com -- PHP Internals - PHP Runtime Development Mailing List To unsubscribe, visit: http://www.php.net/unsub.php
