PHP Intelephense class method loading?

Question

PHP

I recently switched to vscode, it became interesting how to chain methods from a bunch of my classes that are declared outside the current file ...
I found such an approximate solution

/**
* @var TPL $tpl
*/

$tpl->

But writing in each file all the possible classes that you want to use here - this does not suit me.

Is there a solution?
Will buying a premium version of Intelepense help?
Maybe I just don't know how to cook vs code?

It is desirable to have minimal expenses and only legal software...
