The stream extension of PHP is one of the batteries included in its packaging: a uniform interface to access many different types of data, relying on the common abstraction of a stream (not unlike, for example, Java's InputStream and OutputStream). It is not an object-oriented interface, but it is uniform across resource types, allowing reads and writes on files, processes, TCP sockets, and more; it's still polymorphism in action.
