In this blog post, we will see how to get the list of all the categories in Magento2 using object manager.

Please find the below code snippet to achieve this.

$objectManager = \Magento\Framework\App\ObjectManager::getInstance();

// get list of all the categories

$categories = $objectManager->get(‘\Magento\Catalog\Model\ResourceModel\Category\CollectionFactory’)->create();
$categories->addAttributeToSelect(‘*’);

foreach ($categories as $category) {
echo ‘Catgeory Id: ‘.$category->getId() . ‘
‘;
echo ‘Catgeory Name: ‘.$category->getName() . ‘
‘;
echo ‘Catgeory Url: ‘.$category->getUrl() . ‘
‘;
}

// Get current store categories
$categoryHelper = $objectManager->get(‘\Magento\Catalog\Helper\Category’);
$categories = $categoryHelper->getStoreCategories();

foreach ($categories as $category) {
echo ‘Catgeory Id: ‘.$category->getId() . ‘
‘;
echo ‘Catgeory Name: ‘.$category->getName() . ‘
‘;
}

That’s it!
