I don't expect VSCode to be as powerful as PHPStorm but in some projects it's almost as useless as a vanilla text editor.
I've been using Intelliphense and some PHP beautifiers. Recently I tried Devsense which looks more capable of understanding some old code (Yii 2) even though the RAM usage is 10 times higher than VSCode itself.
So while I try different configs I thought about asking here to see echat what other people use.
