Code

<?php
function taxonomy_get_vocabularies($type = NULL) {
  if ($type) {
    $result = db_query(db_rewrite_sql("SELECT v.vid, v.*, n.type FROM {vocabulary} v LEFT JOIN {vocabulary_node_types} n ON v.vid = n.vid WHERE n.type = '%s' ORDER BY v.weight, v.name", 'v', 'vid'), $type);
  }
  else {
    $result = db_query(db_rewrite_sql('SELECT v.*, n.type FROM {vocabulary} v LEFT JOIN {vocabulary_node_types} n ON v.vid = n.vid ORDER BY v.weight, v.name', 'v', 'vid'));
  }

  $vocabularies = array();
  $node_types = array();
  while ($voc = db_fetch_object($result)) {
    // If no node types are associated with a vocabulary, the LEFT JOIN will
    // return a NULL value for type.
    if (isset($voc->type)) {
      $node_types[$voc->vid][$voc->type] = $voc->type;
      unset($voc->type);
      $voc->nodes = $node_types[$voc->vid];
    }
    elseif (!isset($voc->nodes)) {
      $voc->nodes = array();
    }
    $vocabularies[$voc->vid] = $voc;
  }

  return $vocabularies;
