Zend\Http is a primary foundational component of Zend Framework.
Since much of what PHP does is web-based, specifically HTTP, it makes sense to have a
performant, extensible, concise and consistent API to do all things HTTP. In nutshell,
there are several parts of
classes that expose a fluent API for introspecting several aspects of HTTP
Request line information and response status information
Parameters, such as those found in POST and GET
A Client implementation with various adapters that allow for sending requests and introspecting responses.
The Request, Response and Headers portion of the
component provides a fluent, object-oriented interface for introspecting information
from all the various parts of an HTTP request or HTTP response. The two main objects
Zend\Http\Response. These two classes are "context-less",
meaning that they model a request or response in the same way whether it is presented by
a client (to send a request and receive a
response) or by a server (to receive a request and
send a response). In other words, regardless of the context, the
API remains the same for introspecting their various respective parts. Each attempts to
fully model a request or response so that a developer can create these objects from a
factory, or create and populate them manually.
