[php] How to get store information in Magento?

In Magento, how can I get active store information, like store name, line number, etc?

Magento Store Id : Mage::app()->getStore()->getStoreId();

Magento Store Name : Mage::app()->getStore()->getName();

Just for information sake, in regards to my need... The answer I was looking for here was:

Mage::app()->getStore()->getGroup()->getName()

That is referenced on the admin page, where one can manage multiple stores... admin/system_store, I wanted to retrieve the store group title...

You can get active store information like this:

Mage::app()->getStore();  // for store object
Mage::app()->getStore()->getStoreId;  // for store ID

Great answers here. If you're looking for the default view "Store Name" set in the Magento configuration:

Mage::app()->getStore()->getFrontendName()

Get store data

Mage::app()->getStore();

Store Id

Mage::app()->getStore()->getStoreId();

Store code

Mage::app()->getStore()->getCode();

Website Id

Mage::app()->getStore()->getWebsiteId();

Store Name

Mage::app()->getStore()->getName();

Store Frontend Name (see @Ben's answer)

Mage::app()->getStore()->getFrontendName();

Is Active

Mage::app()->getStore()->getIsActive();

Homepage URL of Store

Mage::app()->getStore()->getHomeUrl();

Current page URL of Store

Mage::app()->getStore()->getCurrentUrl();

All of these functions can be found in class Mage_Core_Model_Store

File: app/code/core/Mage/Core/Model/Store.php

In Magento 1.9.4.0 and maybe all versions in 1.x use:

Mage::getStoreConfig('general/store_information/address');

and the following params, it depends what you want to get:

• general/store_information/name
• general/store_information/phone
• general/store_information/merchant_country
• general/store_information/address
• general/store_information/merchant_vat_number

If You are working on Frontend Then Use:

$currentStore=Mage::app()->getStore(); 

If You have store id then use

$store=Mage::getmodel('core/store')->load($storeId);
