Magento 2 Get Current Store ID, Code, Name, Website ID, URL

Sometimes, during Magento 2 customization you need to get the store Information programmatically. You may need to get a current Store ID, Store Code, Name, Website ID, or current URL. 

To retrieve this data use the singleton instance of the following class:

\Magento\Store\Model\StoreManagerInterface

For example, you can include it in your class constructor and then call:

<?php

namespace \MyCompany\ExampleModule\Model;

class Example
{
    private $storeManager;

    public function __construct(
        ...        
        \Magento\Store\Model\StoreManagerInterface $storeManager,        
        ...
    ) {
        ...
        $this->storeManager = $storeManager;        
        ...
    }
    /**
     * Examples
     */
    public function execute()
    {
       /* Get Current Store ID */
       $storeId = $this->storeManager->getStore()->getId();

       /* Get Current Store Code */
       $storeCode = $this->storeManager->getStore()->getCode();

       /* Get Current Store Name */
       $storeName = $this->storeManager->getStore()->getName();

       /* Get Current Store Status */
       $isActive = $this->storeManager->getStore()->isActive();

       /* Get Current Website ID */
       $websiteId = $this->storeManager->getStore()->getWebsiteId();

       /* Get Current URL */
       $currentUrl = $this->storeManager->getStore()->getCurrentUrl();

       /* Get Login Page URL */
       $loginPageUrl = $this->storeManager->getStore()->getUrl('customer/account/login');

       /* Get Code of Store With ID 2 */
       $secondStoreCode = $this->storeManager->getStore(2)->getCode();

    }
}

You can use the object manager to quickly get the StoreManager object for a test, as in the example bellow:

$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$storeManager = $objectManager->get(\Magento\Store\Model\StoreManagerInterface::class);

Attention! If you want to use the StoreManager inside a block class and the block is extended from \Magento\Framework\View\Element\Template, then StoreManager is available for you out of the box through protected property $this->_storeManager. 

Example:

<?php

namespace \MyCompany\ExampleModule\Block;

class Example extends \Magento\Framework\View\Element\Template
{

    public function getCurrentStoreId()
    {
       /* Get Current Store ID */
       return $this->_storeManager->getStore()->getId();
    }
}

Except for the current store ID, code, name and website ID, URL, you need to know how to get URLs in Magento .phtml file.
