 New Comment:

Thats how the OO is designed, internally is interfaces just a class with
an additional flag.

So no bug here

Description:
------------
When I try to define a particular class it fails with "cannot redeclare
class ...". When I check with class_exists('...') it returns false, but
I still cannot create it. I eventually found some previous code which
uses the same name to define an interface.

Test script:
---------------
Interface Singleton{public static function instance();}
if (class_exists('Singleton')) {
    $reason = 'class already exists';
} else {
    class Singleton{
        static function getInstance(){
            return true;
        }
    }
}

Expected result:
----------------
If it is not possible to define a class and an interface with the same
name, then the class_exists() function should also include interface
names.

If it IS possible to have a class and an interface with the same name,
then the compiler should NOT reject the second reference.
