=================================
Opauth is a multi-provider authentication framework for PHP, inspired by [OmniAuth for Ruby](https://github.com/intridea/omniauth).

Opauth enables PHP applications to do *user authentication* with ease.

Try out Opauth for yourself at http://opauth.org

[![Build Status](https://secure.travis-ci.org/opauth/opauth.png?branch=master)](http://travis-ci.org/opauth/opauth)

What is Opauth?
---------------
Opauth provides a standardized method for PHP applications to interface with authentication providers.

Opauth as a framework provides a set of API that allows developers to [create strategies](https://github.com/opauth/opauth/wiki/Strategy-Contribution-Guide) that work in a predictable manner across PHP frameworks and applications.

Opauth works well with other PHP applications & frameworks. It is currently supported on:

- [vanilla (plain) PHP applications](https://github.com/opauth/opauth/tree/master/example)
- [CakePHP](https://github.com/uzyn/cakephp-opauth) (maintained by [uzyn](https://github.com/uzyn))
- [CodeIgniter](https://github.com/destinomultimedia/ci_opauth) (maintained by [destinomultimedia](https://github.com/destinomultimedia))
- [CodeIgniter](https://github.com/mcatm/Opauth-Plugin-for-Codeigniter) (maintained by [mcatm](https://github.com/mcatm))
- [FuelPHP](https://github.com/andreoav/fuel-opauth) (maintained by [andreoav](https://github.com/andreoav/))
- [Laravel](https://github.com/FakeHeal/opauth-laravel) (maintained by [FakeHeal](https://github.com/FakeHeal/))
- [PrestaShop](https://github.com/Onasusweb/PrestaShop-Opauth) (maintained by [Onasusweb](https://github.com/Onasusweb))
- [Silex](https://github.com/icehero/silex-opauth) (maintained by [icehero](https://github.com/icehero/))
- [SilverStripe](https://github.com/BetterBrief/silverstripe-opauth) (maintained by [Better Brief](https://github.com/BetterBrief))
- [Zend Framework 2](https://github.com/lorenzoferrarajr/LfjOpauth) (maintained by [lorenzoferrarajr](https://github.com/lorenzoferrarajr))
- and more to come.

If your PHP framework of choice is not yet listed, you can still use Opauth like you would a normal PHP component (class).

Quick start
-----------
Guide on how to run the bundled example.

1. Set `DocumentRoot` of your web server to `example/`.
(Opauth can be instantiated in your own PHP app, but we will leave that out of this quick start guide)

2. Configure Opauth.

First, make a copy of opauth config's file by copying or renaming
`opauth.conf.php.default` to `opauth.conf.php`.

Open up `opauth.conf.php` and make the necessary changes.

3. Install some [Opauth strategies](https://github.com/opauth/opauth/wiki/List-of-strategies).
Place the strategy files in `lib/Opauth/Strategy/`.

For this example, we recommend that you start with [Opauth-Facebook](https://github.com/opauth/facebook):

i. [Download the strategy files](https://github.com/opauth/facebook/zipball/master) and place them at `lib/Opauth/Strategy/Facebook/`.

ii. Follow the steps at [Opauth-Facebook's README](https://github.com/opauth/facebook/blob/master/README.md) to set up your Faceobok app.

iii. Add the following at `opauth.conf.php` under `Strategy` as such:

```php
array(
// Define strategies here.

'Facebook' => array(
'app_id' => 'YOUR APP ID',
'app_secret' => 'YOUR APP SECRET'
),
);
```

Finally, send user to `http://localhost/facebook` to authenticate.

Check out [the wiki](https://github.com/opauth/opauth/wiki) for more in-depth details, especially on how to use Opauth with your own PHP application.

Available strategies
--------------------
A strategy is a set of instructions that interfaces with respective authentication providers and relays it back to Opauth.
