LightOpenID

Lightweight PHP5 library for easy OpenID authentication., _(*1)

• Version....: 1.1.2 :arrow_double_down: ( see the change log for details )
• Released on: January 15, 2013
• Source code: Gitorious :link:   [GitHub :octocat:][4]
• Homepage...: http://code.google.com/p/lightopenid/
• Author.....: Mewp (http://mewp.s4w.pl/)

Quick start

Sign-on with OpenID in just 2 steps:

1. Authentication with the provider:, _(*2)

   ```php $openid = new LightOpenID('my-host.example.org');, <sub>(*3)</sub>

   $openid->identity = 'ID supplied by user';, <sub>(*4)</sub>

   header('Location: ' . $openid->authUrl()); ```, <sub>(*5)</sub>

2. Verification:, <sub>(*6)</sub>

   ```php $openid = new LightOpenID('my-host.example.org');, <sub>(*7)</sub>

   if ($openid->mode) { echo $openid->validate() ? 'Logged in.' : 'Failed!'; } ```, <sub>(*8)</sub>

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:, <sub>(*9)</sub>

php $openid->required = array('namePerson/friendly', 'contact/email'); $openid->optional = array('namePerson/first');, <sub>(*10)</sub>

Note that if the server supports only SREG or OpenID 1.1, these are automaticaly mapped to SREG names. To get the values use:, <sub>(*11)</sub>

php $openid->getAttributes();, <sub>(*12)</sub>

For more information see USAGE.md., <sub>(*13)</sub>
