Get all the subcategories of any category in Magento.

If you have a category ID (current category OR any category) then you can easily get all the subcategories of that particular category.

Below code will load all the subcategories of the current category. You can even get all the subcategories of any specific category by assigning category ID to $catID.

$catID = $current_category->getId(); //or any specific category id, e.g. 5  
$children = Mage::getModel(‘catalog/category’)->getCategories($catID);  
foreach ($children as $category) {  
 echo $category->getId();  
 echo $category->getName();  
 echo $category->getRequestPath();  
 print_r($category->getData());  
}
