Digg API: Showing latest stories from your site/URL/domain

To do: To show a list of the latest stories from your site/URL/domain using the Digg API.

Solution:

The following PHP code will display the latest 20 stories from the domain of your choice. Thanks a heap to Web Cash’s entry on grabbing a random Digg story as well as the Digg Story API which helped with this code.

<?php
//  Takes an array of arguments and returns a query string
//  Each parameter's name is its key in the array
function buildQuery ($args) {
  $query = '?';
  foreach ($args as $key => $val) {
    if ( $query != '?' )
      $query .= '&';

    $query .= $key . '=' . urlencode($val);
  }

  return $query;
}

// Digg specifies that user agent must be set
ini_set('user_agent', 'My domain stories/1.0');

$baseurl = 'http://services.digg.com';
$endpoint = '/stories';
$url = $baseurl . $endpoint;
// Number of stories to display
$numberStories = 20;
// Your domain of choice - CHANGE THIS
$domainName = 'your.domain.com'; 

//  Parameters to fetch latest articles
$params = array();
$params['appkey'] = 'http://' . $domainName;
$params['domain'] = $domainName;
$params['type'] = 'xml';

$params['count'] = '' . $numberStories;
// The following displays the newest items first
// This can be changed using the parameters in the Digg API
$params['sort'] = 'submit_date-desc'; 

//  Reuse the $url created above
$query = buildQuery($params);
$reqUrl = $url . $query;

// Display the URL. Uncomment for troubleshooting.
// echo $reqUrl . "\n";

$xml = simplexml_load_file($reqUrl);

//  Output the stories
for ($i=0; $i<$numberStories;$i++) {
  $numberDiggs = intval($xml->story[$i]['diggs']);
  echo '<p>';
  echo '<h2><a href="' . $xml->story[$i]['href'] . '">'
    . $xml->story[$i]->title . '</a></h2>';

  // Number of Diggs
  echo '<b>Diggs: ' . $xml->story[$i]['diggs'] . ' ' ;
  // If you don't have an image for number of diggs,
  // then uncomment the following line
  for ($j=0; $j<$numberDiggs; $j++) echo '<img src="digg.gif"> ';
  echo '</b><br />';

  echo 'Date: ' . date('m-d-Y, H:i:s', (int) $xml->story[$i]['submit_date']) . '<br />';
  echo 'Link: <a href="' . $xml->story[$i]['link'] . '">'
    . $xml->story[$i]['link'] . '</a><br />';
  echo 'Topic: ' . $xml->story[$i]->topic['name'] . '<br />';
  echo 'Container: ' . $xml->story[$i]->container['name'] . '<br />';
  echo 'Desc: ' . $xml->story[$i]->description . "</p>\n";
}
?>
