Multi-provider authentication framework for PHP

Opauth is a multi-provider authentication framework for PHP, inspired by OmniAuth for Ruby., _(*1)

Opauth enables PHP applications to do user authentication with ease., _(*2)

Try out Opauth for yourself at http://opauth.org, _(*3)

, _(*4)

What is Opauth?

Opauth provides a standardized method for PHP applications to interface with authentication providers., _(*5)

Opauth as a framework provides a set of API that allows developers to create strategies that work in a predictable manner across PHP frameworks and applications., _(*6)

Opauth works well with other PHP applications & frameworks. It is currently supported on:, _(*7)

• vanilla (plain) PHP applications
• CakePHP (maintained by uzyn)
• CodeIgniter (maintained by destinomultimedia)
• CodeIgniter (maintained by mcatm)
• FuelPHP (maintained by andreoav)
• Laravel (maintained by FakeHeal)
• PrestaShop (maintained by Onasusweb)
• Silex (maintained by icehero)
• SilverStripe (maintained by Better Brief)
• Zend Framework 2 (maintained by 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)., _(*8)

Quick start

Guide on how to run the bundled example., _(*9)

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), _(*10)

2. Configure Opauth., _(*11)

   First, make a copy of opauth config's file by copying or renaming opauth.conf.php.default to opauth.conf.php., _(*12)

   Open up opauth.conf.php and make the necessary changes., _(*13)

3. Install some Opauth strategies. Place the strategy files in lib/Opauth/Strategy/., _(*14)

   For this example, we recommend that you start with Opauth-Facebook:, _(*15)

   i. Download the strategy files and place them at lib/Opauth/Strategy/Facebook/., _(*16)

   ii. Follow the steps at Opauth-Facebook's README to set up your Faceobok app., _(*17)

   iii. Add the following at opauth.conf.php under Strategy as such:, _(*18)

<?php
'Strategy' => 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., _(*19)

Check out the wiki for more in-depth details, especially on how to use Opauth with your own PHP application., _(*20)
