Hi,
today I saw a note left by a person in the documentation on php.net
about the lack of function named interface_exists(). Currently there is
class_exists() which returns true always when the name is a declared
class or a known interface. However an interface is not a class, some
will say that it is a pure abstract class - that's true but the name is different
and we already have abstract classes. In addition classes and interfaces
are differentiated by get_declared_classes() and get_declared_interfaces().
There is a small BC in the case since the patch also makes class_exists()
to return false when the name is a name of a known interface. We are
only 2 months from 5.0.0 and this fix inconsitency. The patch is agains 5.1.0-dev
but can be easily used against 5.0.2-dev .
I will be very happy if it will be accepted and someone with karma commits it.
The patch is here :

Thanks,
