ID: 50699 Comment by: benjamin dot morel at strictcoding dot co dot uk Reported by: gmblar+php at gmail dot com Summary: Cannot throw Exceptions in __toString() Status: Not a bug Type: Bug Package: *General Issues Operating System: * PHP Version: 5.3.1 Block user comment: N Private report: N New Comment: @bjori The documentation does not say that __toString() must not throw an exception. The fact is, this is currently an undocumented behaviour, that could therefore be changed without causing much pain (we're supposed to write code based on the documented behaviour of a function, not its side effects): http://php.net/manual/en/language.oop5.magic.php#object.tostring A feature request has been open, I would be grateful if you could give your opinion there, especially now than PHP 5.5 is being developed: https://bugs.php.net/bug.php?id=53648 Thank you.
