Overview

Requirements

  1. PHP 5.4.0
  2. To use the PHP stream handler, allow_url_fopen must be enabled in your system's php.ini.
  3. To use the cURL handler, you must have a recent version of cURL >= 7.19.4 compiled with OpenSSL and zlib.

Note

Guzzle no longer requires cURL in order to send HTTP requests. Guzzle will use the PHP stream wrapper to send HTTP requests if cURL is not installed. Alternatively, you can provide your own HTTP handler used to send requests.

Installation

The recommended way to install Guzzle is with Composer. Composer is a dependency management tool for PHP that allows you to declare the dependencies your project needs and installs them into your project.

# Install Composer
curl -sS https://getcomposer.org/installer | php

You can add Guzzle as a dependency using the composer.phar CLI:

php composer.phar require guzzlehttp/guzzle:~6.0

Alternatively, you can specify Guzzle as a dependency in your project's existing composer.json file:

 {
   "require": {
      "guzzlehttp/guzzle": "~6.0"
   }
}

After installing, you need to require Composer's autoloader:

require 'vendor/autoload.php';

You can find out more on how to install Composer, configure autoloading, and other best-practices for defining dependencies at getcomposer.org.

Bleeding edge

During your development, you can keep up with the latest changes on the master branch by setting the version requirement for Guzzle to ~6.0@dev.

{
   "require": {
      "guzzlehttp/guzzle": "~6.0@dev"
   }
}

Contributing

Guidelines

  1. Guzzle utilizes PSR-0, PSR-1, PSR-2, and PSR-7.
  2. Guzzle is meant to be lean and fast with very few dependencies. This means that not every feature request will be accepted.
  3. Guzzle has a minimum PHP version requirement of PHP 5.4. Pull requests must not require a PHP version greater than PHP 5.4 unless the feature is only utilized conditionally.
  4. All pull requests must include unit tests to ensure the change works as expected and to prevent regressions.

Running the tests

In order to contribute, you'll need to checkout the source from GitHub and install Guzzle's dependencies using Composer:

git clone https://github.com/guzzle/guzzle.git
cd guzzle && curl -s http://getcomposer.org/installer | php && ./composer.phar install --dev

Guzzle is unit tested with PHPUnit. Run the tests using the Makefile:

make test

Note

You'll need to install node.js v0.5.0 or newer in order to perform integration tests on Guzzle's HTTP handlers.

Reporting a security vulnerability

We want to ensure that Guzzle is a secure HTTP client library for everyone. If you've discovered a security vulnerability in Guzzle, we appreciate your help in disclosing it to us in a responsible manner.

Publicly disclosing a vulnerability can put the entire community at risk. If you've discovered a security concern, please email us at security@guzzlephp.org. We'll work with you to make sure that we understand the scope of the issue, and that we fully address your concern. We consider correspondence sent to security@guzzlephp.org our highest priority, and work to address any issues that arise as quickly as possible.

After a security vulnerability has been corrected, a security hotfix release will be deployed as soon as possible.
