PHPstack now works with SE API v0.9 and includes functions to retrieve data from StackAuth.

Example of StackAuth `sites` function:

    <?php
      //assume $so is our PHPstack class
      $sites = $so->sites();
      foreach($sites->body->api_sites as $site) {
        echo $site->name;
      }
    ?>
