I have projects on two servers. One has PHP 5.4, other has 5.5. First one got APC, second got opcache.
If I have Yii2 project on PHP 5.5 server, do I use yii\caching\ApcCache ? Do I have to install APC on server with opcache ? If not, do I use fileCache with just opcache enabled in background ? I prefer using APC over File, but what to do on 5.5 with opcache ?
