Reported By: mfischer@php.net
Status: Verified
Bug Type: Documentation problem
Operating System: Any
PHP Version: PHP5.2.0
New Comment:
No you shouldn't.
IMO it's quite clear that __toString wouldn't be called
with %i or %e or anything else than %s. But I guess there
is no harm in documenting that too..

I had a small conversation with the autor on internals@ and it is very
important, because you gave the printf example, that __toString() will
only be called if an stirng modified %s is encountered. If it's %d for
integer, __toString() is not called.
This may or may not be expected, but it's the current implementation.
Should I file another report for it?

http://php.net/oop5.magic#language.oop5.magic.tostring
needs an updated before 5.2.0.
#1 Can't throw exceptions anymore
#2 Is called 'wherever it's appropriate' (e.
printf("__toString: %s", $obj))
If language.exceptions will be updated to note where
exceptions can't be thrown it'll need to note lot more then
just __toString()

Description:
------------
From zend_object_handlers.c:
zend_error(E_ERROR, "Method %v::__toString() must not throw an
exception", ce->name);
This is due the recent changes that from now on __toString will be
called everywhere an object is used in a string context.
Good page candidates are:
