string $id

The node ID

boolean $keepAsArray

(optional) Keep the result as an array or transform it into a set of DB_NestedSet_Node objects?

Return value

Get SubBranch

$nestedSet =& DB_NestedSet::factory('DB'$dsn$params);
$parent $nestedSet->createRootNode(array('name' => 'root-node'), falsetrue);
$parent2 $nestedSet->createSubNode($parent, array('name' => 'sub-node));
    $parent3 = $nestedSet->createSubNode($parent2, array('
name' => 'sub-node));
$nestedSet->createSubNode($parent3, array('name' => 'sub1'));
$nestedSet->createSubNode($parent3, array('name' => 'sub2'));
$data $nestedSet->getSubBranch($parent2);
Fetch all siblings of the node given by id Important: The node given by ID will also be returned Do a unset($array[$id]) on the result if you don't want that (Previous) See if a given node is a parent of another given node (Next)
