Get Administrators Role's User Ids programmatically in Magento 2

Hello Friends!!!
In this article, we will learn how we can get all user ids of the ‘Administrators‘ user role in Magento 2.

Here, to get the user Ids, I have created a method getAdminUserIds in the following Helper class file.
You can add this method to your required class file and can call on the required places in your code.

namespace Webkul\CustomModule\Helper;

use Magento\User\Model\ResourceModel\User\CollectionFactory as UserCollectionFactory;

/**

class Data extends \Magento\Framework\App\Helper\AbstractHelper
{
    /**
     * const ADMIN_ROLE

    private const ADMIN_ROLE = "Administrators";

    /**
     * @var UserCollectionFactory
     */
    private $userCollFactory;

    /**
     * Constructor
     *
     * @param UserCollectionFactory $userCollFactory

     */
    public function __construct(
        UserCollectionFactory $userCollFactory,
        \Magento\Framework\App\Helper\Context $context
    ) {
        $this->userCollFactory = $userCollFactory;
        
        parent::__construct($context);
    }

    /**
     * Get Administrator Role's user ids
     *
     * @return array
     */
    public function getAdminUserIds()
    {
        $ids = [];
        try {
            $userColl = $this->userCollFactory->create()
                ->addFieldToSelect("user_id");
           
            $userColl->getSelect()
                ->where("`detail_role`.`role_name` = '".(self::ADMIN_ROLE).
                "' AND user_role.parent_id=detail_role.role_id");

            $userIdsColl = (!empty($userColl))?$userColl->getData():[];

            foreach ($userIdsColl as $each) {
                $ids[] = $each["user_id"] ?? 0;
            }
        } catch (\Exception $e) {
            //to do here
        }
        return $ids;
    }
}

Hope this will be helpful.
Thanks 🙂
