<?php

class Mendeley {  
  static function fetch($path, $params = array()) {    
    $default = array('consumer_key' => MENDELEY_CONSUMER_KEY);
    $url = 'http://api.mendeley.com/oapi/' . $path . '?' . http_build_query($params + $default);     
    return json_decode(file_get_contents($url), true);
  }
  
  // http://apidocs.mendeley.com/home/public-resources/search-details
  static function document($id, $type = null) {
    if ($type == 'doi') $id = str_replace('/', '%2F', $id); // workaround
    return self::fetch('documents/details/' . rawurlencode($id), array('type' => $type));
  }
  
  // http://apidocs.mendeley.com/home/public-resources/public-groups-details
  static function group($id, $section = 'main') {

  }
}

$data = Mendeley::document('10.1038/nchem.1140', 'doi'); // an example DOI
print_r($data);

$data = Mendeley::group(630791); // an example group ID
print_r($data);
