How to get the ID of a store by name?

Question

Let´s say I have a store named "Megastore". How can I get the id of that specific store?

Can I do it by using some kind of filter?

Mage::getModel('core/store')->addFieldToFilter('name', 'Megastore');

Answer 1

Actually found the solution here: How to get the store id from the code

Mage::app()->getStore('Megastore')->getId()

Answer 2

What do you need the ID for? Are you writing code for a specific store? If so you can do

  <?php if (Mage::app()->getStore()->getCode() == 'default'){ ?>

Default being the store name.
