Check if EE version or CE by code

Question

Is there a clean way to make a difference code wise between EE and CE?
The problem.
I'm updating an extension so it will work nicely on ce-1.9.
The extension is not for EE, but it seams to work on that also.
For the update I need to create an upgrade script that should be executed only if installed on CE-1.9 (or EE 1.14).
I cannot simply check

version_compare(Mage::getVersion, '1.9', '>=');

because this will be triggered in EE 1.9+ and I don't want that.

Right now I'm using this:

$isEE = Mage::helper('core')->isModuleEnabled('Enterprise_Enterprise');

but it seams kind of ugly.

Any other ways to check?

Answer 1

Since CE 1.7 you have Mage::getEdition() that gives this information:

/**
 * Magento edition constants
 */
const EDITION_COMMUNITY    = 'Community';
const EDITION_ENTERPRISE   = 'Enterprise';
const EDITION_PROFESSIONAL = 'Professional';
const EDITION_GO           = 'Go';

/**
 * Current Magento edition.
 *
 * @var string
 * @static
 */
static private $_currentEdition = self::EDITION_COMMUNITY;



/**
 * Get current Magento edition
 *
 * @static
 * @return string
 */
public static function getEdition()
{
   return self::$_currentEdition;
}

One other possible way is to navigate to root folder of magento 1 installation and run the following command in CLI.

php -r "require 'app/Mage.php'; echo Mage::getEdition(); "

Alternativelly if you want to get also the version

php -r "require 'app/Mage.php'; echo Mage::getEdition(); echo Mage::getVersion();"

works just fine.
