Introduction

zend-http provides the HTTP message abstraction used by zend-mvc, and also provides an extensible, adapter-driven HTTP client library. It provides the following abstractions:

• Context-less Request and Response classes that expose a fluent API for introspecting several aspects of HTTP messages:
  • Request line information and response status information
  • Parameters, such as those found in POST and GET
  • Message Body
  • Headers
• A client implementation with various adapters that allow for sending requests and introspecting responses.

Not PSR-7!

This library does not support PSR-7, as it predates that specification. For PSR-7 support, please see our Diactoros component.

Zend\Http Request, Response and Headers

The request, response and headers implementations of the zend-http component provides a fluent, object-oriented interface for introspecting information from all the various parts of an HTTP request or HTTP response. The primary classes are Zend\Http\Request and Zend\Http\Response. Both 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.
