Working on the categories for a magento homepage for pulling out categories on the main page.

At the moment it pulls all out of the categories out but I want to limit this too 6 categories.

I have tried a few different options and have not been able to get this working correctly.

What would be the best way to apply the limit? I have included code below.

<ul class="cat-nav">

<?php

    $obj = new Mage_Catalog_Block_Navigation();

    $storeCategories = $obj->getStoreCategories();

    Mage::registry('current_category') ? $currentCategoryId = Mage::registry('current_category')->getId() : $currentCategoryId='';

    foreach ($storeCategories as $_category):

?>

        <li class="<?php echo $_category->getName(); ?>">



            <?php $categoryChildren = $_category->getChildren(); ?>

            <?php if($categoryChildren->count()) : ?>

                <ul>



                    <?php foreach($categoryChildren as $_categoryChild) : ?>

                        <?php $_categoryChildModel = Mage::getModel('catalog/category')->load($_categoryChild->getId());?>

                        <?php $categoryGrandchildren=$_categoryChild->getChildren(); ?>

                        <li class="<?php echo $_category->getName(); ?>">

                            <?php

                                $currentCategoryId===$_categoryChild->getId() ? $bold="style="font-weight:bold"" : $bold='';

                                echo '&emsp;' . '<a href="' . $_categoryChildModel->getUrl() . '"' . $bold . '>' .  $_categoryChild->getName() . '' . $_categoryChildModel->getProductCollection() . '</a>';

                            ?>

                        </li>

                        <?php if($categoryGrandchildren->count()) : ?>

                            <?php foreach($categoryGrandchildren as $_categoryGrandchild) : ?>

                                <?php $_categoryGrandchildModel = Mage::getModel('catalog/category')->load($_categoryGrandchild->getId());?>

                                <li>

                                    <?php

                                        $currentCategoryId===$_categoryChild->getId() ? $bold="style="font-weight:bold"" : $bold='';

                                        echo '&emsp;&emsp;' . '<a href="' . $_categoryGrandchildModel->getUrl() . '"' . $bold . '>' .  $_categoryGrandchild->getName() . '(' . $_categoryGrandchildModel->getProductCount() . ')</a>';

                                    ?>

                                </li>

                            <?php endforeach; ?>

                        <?php endif; ?>

                    <?php endforeach; ?>

                </ul>

            <?php endif; ?>

        </li>

    <?php endforeach ?>

</ul>

You can get a list of categories based on the parent id like this:

$parentId = 'Your parent id here';

$categories = Mage::getModel('catalog/category')

    ->getCollection()

    ->addAttributeToSelect('*')

    ->addAttributeToFilter('parent_id', $parentId)

    ->addAttributeToFilter('is_active', 1)

    ->addAttributeToSort('position')

    ->setCurPage(1)->setPageSize(6);//limit to 6 categories

To get the root categories use $parentId = Mage::app()->getStore()->getRootCategoryId().

For the sub categories use $parentId = 'the category id for which you are trying to retrieve the child categories.'
