Quick start
-----------

[](#quick-start)

### Sign-on with OpenID in just 2 steps:

[](#sign-on-with-openid-in-just-2-steps)

1. Authentication with the provider:

    ```
    $openid = new LightOpenID('my-host.example.org');

    $openid->identity = 'ID supplied by user';

    header('Location: ' . $openid->authUrl());
    ```
2. Verification:

    ```
    $openid = new LightOpenID('my-host.example.org');

    if ($openid->mode) {
      echo $openid->validate() ? 'Logged in.' : 'Failed!';
    }
    ```

### Support for AX and SREG extensions:

[](#support-for-ax-and-sreg-extensions)

To use the AX and SREG extensions, specify `$openid->required` and/or `$openid->optional`before calling `$openid->authUrl()`. These are arrays, with values being AX schema paths (the 'path' part of the URL). For example:

```
$openid->required = array('namePerson/friendly', 'contact/email');
$openid->optional = array('namePerson/first');
```

Note that if the server supports only SREG or OpenID 1.1, these are automaticaly mapped to SREG names. To get the values use:

```
$openid->getAttributes();
```

For more information see [USAGE.md](http://github.com/iignatov/LightOpenID/blob/master/USAGE.md).
