How to set up the environment?

Question

phpstorm

There are two questions
1) When typing functions, the environment does not show any hints, neither the names of functions on the fly, nor the type of parameters, much less the description. When you hover over an already written
function, nothing happens either. I worked in vs, everything works very well out of the box. If you need to install additional plugins, then which ones are for js, vuejs
2) How to disable warnings about
unused css styles?

Answer 1

You need to do three things - 1) set the project-lvl version of the language (just enter php in the settings, find the menu of the same name, and select the current version).
You don’t need to do this if there is composer.json - it will set it itself during the sync
2) composer.json sync - will pull up all the restrictions (usually this is offered in the lower right corner)
3) specify the folder with the libraries, i.e. Vendor.
You can just select Vendor and click 'mark as -> source root' You can
google about the plugins yourself. There is a list of available plugins right in settings -> plug-ins.
The second point is not clear, explain what you mean or give a screen
