Code

function taxonomy_menu_block_nest_tree($tree, $root = '0') {
  $nested_tree = array();

  // Loop over the tree and search for direct children of the root.
  foreach ($tree as $tid => $term) {

    // Direct child is found.
    if ($term['parents'][0] == $root) {

      // Remove item from tree (we don't need to traverse this again).
      unset($tree[$tid]);

      // Append the child into result array and parse its children.
      $nested_tree[$tid] = $term;
      $nested_tree[$tid]['children'] = taxonomy_menu_block_nest_tree($tree, $tid);
    }
