LightOpenID

Lightweight PHP5 library for easy OpenID authentication.

• Version....: 1.3.1 :arrow_double_down: ( see the change log for details )
• Released on: March 04, 2016
• Source code: Official GitHub Repo :octocat:
• Homepage...: http://code.google.com/p/lightopenid/
• Author.....: Mewp

Quick start

Add to composer.json

"repositories": [
  {
    "type": "vcs",
    "url": "https://github.com/iignatov/LightOpenID"
  }
],

"require": {    
  "php": ">=5.4.0",
  "iignatov/lightopenid": "*"
}

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:

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.
