Detailed Description

This class only acts as shortcut to construct a cache frontend with a null backend. It extends PhpFrontend to be sure it can also be used for all types of caches (also the one requiring a PhpFrontend like "core"). TODO: Instead a factory class should be introduced that replaces this class and \TYPO3\CMS\Core\Core\Bootstrap::createCache
