Get specific category level - magento

Question

How can I get a specific category level from Magento, my category setup looks like this now.
root_catalog
|-Shop
|-Shoes
|-T-shirts
|-Brands
|-Nike
|-Womens
|-Mens
|-Adidas
|-Asics
<?php if( $category = Mage::getModel('catalog/category')->load( $categories[1]) ): ?>
<?php echo $category->getName(); ?>
<?php endif ?>
When calling $category->getName(); I would like to only display the Brand Name, is that possible?

Answer 1

You can get category level from
$category = Mage::getModel('catalog/category')->load( $categories[1]) )->getLevel()
and then check with your brand name category level, if match then display name.
e.g. suppose brand category level is 3
<?php if( $category = Mage::getModel('catalog/category')->load( $categories[1]) ): ?>
<?php if($category->getLevel() == 3)
echo $category->getName(); ?>
<?php endif ?>
<?php endif ?>

Answer 2

ANKIT's answer is good, but it could be improved by actually query-ing the specific levels instead of loading the whole collection and doing a conditional. Take for example if you want to get all categories in a specific level:
<ul>
<?php $categories = Mage::getModel('catalog/category')
->getCollection()
// magic is prepared here..
->addAttributeToSelect('*')
// then the magic happens here:
->addAttributeToFilter('level', array('eq'=>2))
->load();
foreach($categories as $category):
?>
<li>$category->getName()</li>
<?php endforeach; ?>
</ul>

<?php
$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$product = $objectManager->get('Magento\Framework\Registry')->registry('current_product');
$categories = $product->getCategoryIds(); /*will return category ids array*/
foreach($categories as $category){
$cat = $objectManager->create('Magento\Catalog\Model\Category')->load($category);
if ($cat->getLevel() == 2) {
$catName = $cat->getName().","; ?>
<div class="brand_bg">
<label><?php /* #escapeNotVerified */ echo __('Category :') ?></label>
<?php echo $catName; ?>
</div>
<?php } ?>
<?php } ?>
?>
