For each operation in the interface, the proxy object supports a method of the same name. Each operation accepts an optional trailing parameter representing the operation context. This parameter is an associative string array for use by the Ice run time to store information about how to deliver a request. You normally do not need to use it. (We examine the context parameter in detail in Request Contexts. The parameter is also used by IceStorm.)

Interface Inheritance in PHP

Consider the following example:

interface A { ... }
interface B { ... }
interface C extends A, B { ... }

Given a proxy that has been narrowed to C, a client can invoke any operation defined for interface C, as well as any operation inherited from C's base interfaces.
