How work Mage :: helper in Magento?

I tried to understand this line of code.

$_attributes = Mage::helper('core')->decorateArray($this->getAllowAttributes());

1.for started was declared a variable ($_attributes)

2.Mage::helper('core')helper is a method that loads an object? What is core? a file? where to find this file?

3.decorateArray is a method from core class?

Can you tell me please how this code works and give me a simple example?

I tried to make this short example in my page

$_attributes = Mage::helper('core')->decorateArray($this->getAllowAttributes());
<?php if($_product->isSaleable() && count($_attributes)){
   echo "de vanzare";
}
?>

Perhaps the condition is evaluated false message and not displayed. I get no error, but not working.

I wanted to see if I understand how it works Mage::helper (that's why I made this example)

Thanks in advance!

Mage::helper('core') belongs to app/code/core/Mage/Core/Helper. You can find decorateArray() into data.php inside this path.

Mage folder contains core classes for magento.

Mage::helper('myHelper') will load the called helper, here you load the Mage_Core_Helper_Data helper.

$_attributes will contain the result of the function you called, here the function decorateArray which is in Mage_Core_Helper_Data.
