Probbaly, this is most likely causing the next useless/senseless thread with tons of mail replies hitting reply before thinking. Well, we could convert the output of __toString() to an integer but generally that is not the way the engine is designed and most likely causing a lot of unwanted sideeffects. The correct solution would be to add something that allows to hook into engine' object get handler or allow to specify which type the cast handler is supposed to return. Both could be accomplished by an interface and a maybe a bit of stuff to make this work. That said we have enough time for PHP 6.0 and should not do anything in 5.x. best regards marcus > PHP Bug Database wrote: >> ID: 37538 >> Updated by: [EMAIL PROTECTED] >> Reported By: [EMAIL PROTECTED] >> -Status: Open >> +Status: Bogus >> Bug Type: Strings related >> -Operating System: Linux >> +Operating System: * >> -PHP Version: 5CVS-2006-05-21 (CVS) >> +PHP Version: * >> New Comment: >> >> Thank you for taking the time to write to us, but this is not >> a bug.
