php - How do I save value in my own session variable in Magento?

Question

I am using Magento and trying to save a value in the session as follows in its index.php file, but the value is not being retained.

$_SESSION['myvar'] = '1';

How do I do it?

Thanks

Let's say you want to save the value "Hello world" to the "welcome message" variable in the session. The code would be :

$inputMessage = 'Hello World';
Mage::getSingleton('core/session')->setWelcomeMessage($inputMessage);

Now you want to echo the "welcome message" somewhere else in your code/site.

$outputMessage = Mage::getSingleton('core/session')->getWelcomeMessage();
echo $this->__($outputMessage);
