FAQ
===
Why should I use Guzzle?
========================
Guzzle makes it easy to send HTTP requests and super simple to integrate with
web services. Guzzle manages things like persistent connections, represents
query strings as collections, makes it simple to send streaming POST requests
with fields and files, and abstracts away the underlying HTTP transport layer
(cURL, ``fopen()``, etc.). By providing an object oriented interface for HTTP
clients, requests, responses, headers, and message bodies, Guzzle makes it so
that you no longer need to fool around with cURL options or stream contexts.
To get a feel for how easy it is to use Guzzle, take a look at the
:doc:`quick start guide <quickstart>`.
Swappable HTTP Adapters
-----------------------
Guzzle will use the most appropriate HTTP adapter to send requests based on the
capabilities of your environment and the options applied to a request. When
cURL is available on your system, Guzzle will automatically use cURL. When a
request is sent with the ``stream=true`` request option, Guzzle will
automatically use the PHP stream wrapper HTTP adapter so that bytes are only
read from the HTTP stream as needed.
.. note::
Guzzle has historically only utilized cURL to send HTTP requests. cURL is
an amazing HTTP client (arguably the best), and Guzzle will continue to use
it by default when it is available. It is rare, but some developers don't
have cURL installed on their systems or run into version specific issues.
By allowing swappable HTTP adapters, Guzzle is now much more customizable
and able to adapt to fit the needs of more developers.
HTTP Streams
------------
Request and response message bodies use :doc:`Guzzle Streams <streams>`,
allowing you to stream data without needing to load it all into memory.
Guzzle's stream layer provides a large suite of functionality:
- You can modify streams at runtime using custom or a number of
pre-made decorators.
- You can emit progress events as data is read from a stream.
- You can validate the integrity of a stream using a rolling hash as data is
read from a stream.
Event System
------------
Guzzle's flexible event system allows you to completely modify the behavior
of a client or request at runtime to cater them for any API. You can send a
request with a client, and the client can do things like automatically retry
your request if it fails, automatically redirect, log HTTP messages that are
sent over the wire, emit progress events as data is uploaded and downloaded,
sign requests using OAuth 1.0, verify the integrity of messages before and
after they are sent over the wire, and anything else you might need.
Easy to Test
------------
Another important aspect of Guzzle is that it's really
:doc:`easy to test clients <testing>`. You can mock HTTP responses and when
testing an adapter implementation, Guzzle provides a mock web server that
makes it easy.
Large Ecosystem
---------------
Guzzle has a large `ecosystem of plugins <http://guzzle.readthedocs.org/en/latest/index.html#http-components>`_,
including `service descriptions <https://github.com/guzzle/guzzle-services>`_
which allows you to abstract web services using service descriptions. These
service descriptions define how to serialize an HTTP request and how to parse
an HTTP response into a more meaningful model object.
- `Guzzle Command <https://github.com/guzzle/command>`_: Provides the building
blocks for service description abstraction.
- `Guzzle Services <https://github.com/guzzle/guzzle-services>`_: Provides an
implementation of "Guzzle Command" that utlizes Guzzle's service description
format.
Is it possible to use Guzzle 3 and 4 in the same project?
