It's an interesting thought, but we currently have the object keyword for that particular use case. In some languages, having a base object is useful because functionality can be defined there, but PHP provides no way of altering existing classes, limiting that use too.

There’s no such type hint though:

$ php -r 'function foo(object $x) {} foo(new StdClass);’
PHP Catchable fatal error:  Argument 1 passed to foo() must be an instance of object, instance of stdClass given, called in Command line code on line 1 and defined in Command line code on line 1

Perhaps one should be added? Not in this RFC though, obviously.


Oops, my bad, I thought that existed already! :|
