Magento Categories – How to Get Magento Categories by Array of Category IDs

categorysubmenu

I have a situation where i have an array of category ids (containing both parent and child categories). now i want to fetch all categories by ids in the array in parent child relation i.e.
if the category is top level (parent) then print it else if the category is child first get and print its parent category and then print the child categories.
Until now i can get all categories from the list but the condition i applied to check if the category has parent category remain always true as all main categories are child of the root (default) category

<?php if ($_categories->getParentId()>0) {
    $_categories= $_categories->getParentCategory();
} ?>

Based on the comments....
Instead of $_categories->getParentId()>0 try to check

$_categories->getParentId() != 1 && $_categories->getParentId() != Mage::app()->getStore()->getRootCategoryId().

This should exclude the root of all roots (id 1) and the default root category of the store.

Magento 1.9 – Get All Parent Categories of Current Category

let's say that $category is your current category.
You can call $category->getParentCategories() and you will get an instance of Mage_Catalog_Model_Resource_Category_Collection.
You can loop through it and get each category in the tree branch.
You should be able to call ->getLevel() on each of these categories to see how high or low they are in the tree.

[EDIT]
You can do this to loop through all the parent categories

foreach ($category->getParentCategories() as $parent) {
    //do something with $parent.
    if ($parent->getLevel() == 2) {
        //then $parent is a top level category
    }
}
