Proper way to call a model constant in Magento 1

Question

I have the class below:

class Company_Module_Model_Somemodel extends Mage_Core_Model_Abstract
{
    const SOME_CONST = 'constant_text';   
} 

What is the proper and correct way to call the constant in another class? Like this:

$class = Mage::getModel('company_model/somemodel');
echo $class::SOME_CONST;

Or like this:

echo Company_Module_Model_Somemodel::SOME_CONST;

Can you explain why is the one better than other? Thanks!

Answer 1

echo Company_Module_Model_Somemodel::SOME_CONST;

This one is way to go because Magento uses an autoloader and your class will be autoloaded by name

I hope this will help

Answer 2

You can call the constant as :

class ClassName {
    const CONSTANTNAME = 'ConstantValue';
}

Now you can call this constant as echo ClassName::CONSTANTNAME.
