The first method will return the current website, store ID and store name. while the second will return all. Throw into a workbench script to run in isolation: https://gist.github.com/benmarks/4532434
// To output current website, store ID and store name
<?php
echo "Website ID: " . Mage::app()->getWebsite()->getId() . "<br/>";
echo "Website Name: " . Mage::app()->getWebsite()->getName() . "<br/>";
echo "Store ID: " . Mage::app()->getStore()->getId() . "<br/>";
echo "Store Name: ".Mage::app()->getStore()->getName(). "<br/>";
echo "Store code: ". Mage::app()->getStore()->getCode()."<br/>";
?>
// To output all websites, store IDs and store names
foreach (Mage::app()->getWebsites() as $website) {
foreach ($website->getGroups() as $group) {
$stores = $group->getStores();
foreach ($stores as $store) {
echo $store->getId() ." ".$store->getName()."<br/>";
