Breadcrumb add content type data without any modules How could I print content type like the breadcrumb, for example 


  Home/Content type/Create
It is possible using theme_breadcrumb().

Example:

/**
 * Implements theme_breadcrumb().
 */
function theme_breadcrumb($variables) {
  // global variable 
  $output = '';
  $breadcrumb = $variables['breadcrumb'];
  if (!empty($breadcrumb)) {
    $nid = arg(1);
    $node = node_load($nid);
    $output = '&lt;ul class="breadcrumb"&gt;';
      $i = 1;
      foreach($breadcrumb as $value) {
        $output .= '&lt;li class="breadcrumb-'.$i.'"&gt;'.$value.'&lt;/li&gt;';
      $i++;
      }
      if ($node-&gt;type == 'content_type') {
        $output .= '&lt;li&gt;&lt;a href="' . url() . '" rel="breadcrumb"&gt;' .  $node-&gt;type . '&lt;/a&gt;&lt;/li&gt;';
      }
    $output .= '&lt;li class="active"&gt;'. drupal_get_title() .'&lt;/li&gt;';
    $output .= '&lt;/ul&gt;'; 
    return $output;
  }
}
