Get Child categories magento

Question

Trying to get child of a specific category which is active. Please help. I am having trouble doing it. I'm currently able to show them all but not specifically. Would appreciate any help.

$category = Mage::getModel('catalog/category')->load(2);
$category->getChildCategories();
$tree = $category->getTreeModel();
$tree->load();
$ids = $tree->getCollection()->getAllIds();

Answer 2

here is code to load active category

/* Load category by id*/
$cat = Mage::getModel('catalog/category')->load($id);


/*Returns comma separated ids*/
$subcats = $cat->getChildren();

//Print out categories string
#print_r($subcats);

foreach(explode(',',$subcats) as $subCatid)
{
  $_category = Mage::getModel('catalog/category')->load($subCatid);
  if($_category->getIsActive())
  {
    $caturl     = $_category->getURL();
    $catname     = $_category->getName();
    if($_category->getImageUrl())
    {
      $catimg     = $_category->getImageUrl();
    }
    echo '<h2><a href="'.$caturl.'" title="View the products for this category"><img src="'.$catimg.'" alt="" />'.$catname.'</a></h2>';
  }
}
?>

hope this is sure help you.
