What is Opauth?

Opauth provides a standardized interface between PHP applications and authentication providers.

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.

Opauth works well with other PHP applications & frameworks.

Quick start

1. Composer require Opauth core and Opauth strategies. Add the following to your application's composer.json:

   {
       "minimum-stability": "dev",
       "require": {
           "opauth/opauth": "~1.0",
           "opauth/facebook": "~1.0"
       }
   }

   Note: While Opauth 1.0.x still is in development, your root composer.json will need to set its minimum-stability to dev.

   Install them

   $ composer install

2. Configure Opauth.
   Create a file opauth.php that is accessible at http://localhost/opauth.php/.

   <?php
   $config = array(
       'Strategy' => array(
           'Facebook' => array(
               'app_id' => 'YOUR APP ID',
               'app_secret' => 'YOUR APP SECRET'
           )
       ),
       'path' => '/opauth.php/'
   );

3. Instantiate and run Opauth

   <?php
   $Opauth = new Opauth\Opauth\Opauth($config);
   
   try {
       $response = $Opauth->run();
       echo "Authed as " . $response->name . " with uid" . $response->uid;
   } catch (OpauthException $e) {
       echo "Authentication error: " . $e->getMessage();
   }

4. Point your browser to http://localhost/opauth.php/facebook to see it in action.
