[TYPO3-dev] how to iterate over LoadedExtensionArrayElement

[Alexander Stehlik]

Sorry, just got the point with the replacement of the underscore in the 
Extension key.

You can have a look a a patch in gerrit, that is also iterating over the 
active packages:

https://review.typo3.org/#/c/25002/2/typo3/sysext/impexp/Classes/Controller/ImportExportController.php

Code looks basically like:

$packageManager = 
GeneralUtility::makeInstance('TYPO3\\CMS\\Core\\Package\\PackageManager');
foreach ($packageManager->getActivePackages() as $package) {
	$packageKey = $package->getPackageKey();
	... // do your own stuff here
}

Hope this helps.

Cheers,
Alex
