How to get sub-categories of a specific parent category?

I had a main category (parent category) whose id = 10. I want to echo just its sub-categories. How can I do that?

  1. This code may help if you want to get child category of every current category

        <?php 
        $layer = Mage::getSingleton('catalog/layer');
        $_category = $layer->getCurrentCategory();
        $currentCategoryId= $_category->getId();
        $children = Mage::getModel('catalog/category')->getCategories($currentCategoryId);
        foreach ($children as $category)
        {
              echo $category->getName(); // will return category name 
              echo $category->getRequestPath(); // will return category URL
        }
        ?>
    

  2. Another way:

    $children = Mage::getModel('catalog/category')->load(10)->getChildrenCategories();
    foreach ($children as $category):
        $category = Mage::getModel('catalog/category')->load($category->getId());
        echo '<li><a href="' . $category->getUrl() . '">' . $category->getName() . '</a></li>';
    endforeach;
    

  3. <?php 
    $parentCategoryId = 107;
    $cat = Mage::getModel('catalog/category')->load($parentCategoryId);
    $subcats = $cat->getChildren();
    
    // Get 1 Level sub category of Parent category
    foreach(explode(',',$subcats) as $subCatid)
                  {
                    $_category = Mage::getModel('catalog/category')->load($subCatid);
      if($_category->getIsActive()) {
        echo '<ul><a href="'.$_category->getURL().'" title="View the products for the "'.$_category->getName().'" category">'.$_category->getName().'</a>';
       echo '</ul>';
      }
    }
    
    ?>

  4. This is my solution

    <?
        // Project  : 
        // File     :
        // Author   : Hidayet Ok ( hidonet@gmail.com )
    
        require_once('./app/Mage.php');
        Mage::app("default");
    
        $rootcatId  = Mage::app()->getStore()->getRootCategoryId();
        $root_cat   = Mage::getModel('catalog/category')->load($rootcatId);
    
        $categories = get_child_categories($root_cat);
    
        echo "<pre>";
        print_r($categories);
        echo "</pre>";
    
    
        function get_child_categories($parent) {
    
            $cat_model = Mage::getModel('catalog/category');
    
            $categories = $cat_model->load($parent->getId())->getChildrenCategories();
    
            $ret_arr = array();
            foreach ($categories as $cat) 
            {
                $ret_arr[] = array(
                                    'cat_id' => $cat->getId(),
                                    'cat_name' => $cat->getName(),
                                    'cat_url' => $cat->getUrl(),
                                    'child_cats' => get_child_categories($cat),
                                    );
            } // foreach sonu
    
            return $ret_arr;
    
        } // function sonu ##############
    
    
    ?>
    

    and the output is;
