Question

Should an abstract class always be prefixed with Abstract and suffixed with Interface (when it’s an interface)? Is there any standard naming convention, similar to PSR-0 for folder structure/namespaces, but for classes?

It seems redundant as the language has literal keywords for this very purpose.

abstract class AbstractFoo {}

interface InterfaceFoo {}

trait TraitFoo {}

There isn’t a convention for this; especially in PHP. This can all be organized however you’d like.

With the additions of namespaces in PHP 5.3, I don’t see the need to add Abstract or Interface prefixes/suffixes to the actual class names.

Just name things as they are!
