php-comments library

This library takes HTML and converts it to a simple PHP data structure. Example post:

  
  $result = array(
    'type' => 'reply',
    'author' => array(
      'name' => 'Aaron Parecki',
      'photo' => 'http://aaronparecki.com/images/aaronpk.png',
      'url' => 'http://aaronparecki.com/'
    ),
    'published' => '2014-02-16T18:48:17-0800',
    'name' => 'Example Note',
    'text' => 'this text is displayed as the comment',
    'url' => 'http://aaronparecki.com/post/1'
