Why doesn't phpstorm index laravel internals?

Question

phpstorm

Created a project in Laravel. Empty.
I click on the str_random function (and others), writes:
"Cannot find declaration to go to".

Answer 1

Many folders have been excluded from indexing by default. If anyone knows why, please write in the comments.
Removed them from the "excluded" and the problem was solved.

Answer 3

@deprecated Str::random() should be used directly instead. Will be removed in Laravel 6.0.
I'll translate if you don't understand.
Laravel version 6.0 will remove the str_random() global function. Use via the Str::random() helper.
In your case, it is not clear which version of Laravel you have and why the storm is not indexing.

Answer 4

Well, here it is possible that the storm itself did not index. Try demolishing the vendor folder and then composer update.
After that, the storm should re-index everything.
