Vscode-intelephense: PHP 7.4 arrow functions not supported?!

[SaschaS93]

Describe the bug
With PHP 7.4 arrow functions were introduced. Unfortunately arrow functions are shown as wrong code. Even with runnable code.

To Reproduce
Just create a simple arrow function as a callback. The editor will shown that it's wrong. But with it's working with PHP 7.4.

Expected behavior
The editor shouldn't mark it as an error.

I already tried to change the PHP Version in Intelephense > Environment: PHP Version to 7.4.0 and added "fn" to Intelephense: Stubs. Unfortunately both didn't work.

Screenshots

function test() {
  echo 'hello world';
}

call_user_func(fn() => test());

Platform and version

macOS Mojave
Version 10.14.6

Visual Studio Code
Version 1.42.1

PHP Intelephense
Version 1.3.11

This might be error from build-in php validator from vscode, can you check if you have path to php7.4 in php.validate.executablePath or set "php.validate.enable": false?

Ahh sorry. You're right.

Was working with PHP 7.4 in Docker but I had an older version installed on my local machine.

Sorry. But I wish you a nice weekend! :)

I can't seem to resolve this, I have these configurements:

{
    "php.validate.enable": false,
    "intelephense.environment.phpVersion": "7.4.5",
}

Yet, my IDE complains on the arrow functions:

I've tried to reindex the workspace and restarting VSCode, to no avail. Any ideas?
