Re: Bug #37538 [Opn->Bgs]: toString in sprintf/printf and %d modifier does't work as expected

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 [sorry for sending twice, Marcus, gone through wrong list email] Hi, I expected this to be bogusfied. The thing is ... if you put a normal string for a %d it just works. Now that people learn about __toString() I think it's not clear why %d doesn't work for an object, because also (string)$obj, as Marcus pointed out, works. Is it totally off-side to support objects where also integer would be expected, were usually a string instead of an integer also works? Either by introducing __toInt() [ok, I think I better not suggest this] or at least also call __toString() for integers [which may be actually ever worse idea] or e.g. call __toInt() if available, if not __toString() and if not available -> standard behaviour. Or should I better just not have sent this email? - - Markus PHP Bug Database wrote: > ID: 37538 > Updated by: helly@php.net > Reported By: mfischer@php.net > -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.
