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

假设您要将值“Hello world”保存到会话中的“welcome message”变量中。代码是：

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

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

现在，您希望在代码/站点中的其他位置回显“欢迎消息”。

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

Following the example given by Ali Nasrullah, I would do:

按照Ali Nasrullah给出的例子，我会这样做：

$session = Mage::getSingleton("core/session",  array("name"=>"frontend"));
// set data
$session->setData("device_id", 4);
// get data
$myDeviceId = $session->getData("device_id");

Make sure you include [Mage-root]/app/Mage.php befor calling the code above!

确保在调用上面的代码时包含[Mage-root] /app/Mage.php！

@Ali Nasrullah: Pass the value of device:id as second parameter of the setData function.

@Ali Nasrullah：传递device：id的值作为setData函数的第二个参数。

  Mage::getSingleton('core/session')->setMySessionVariable('MyValue'); 

  $myValue  =  Mage::getSingleton('core/session')->getMySessionVariable();

  echo $myValue;
