Phpshtorm not mark when expression is always false

Could you please share a code example and illustrate what should be marked there?

Vasiliy Yur

in Rider, I see that the inspection marks the expression:

if(!true)
{
   var test = 1;
}

It would be cool to see the same in a Phpshtorm. I want to see marked this:

private function func(array $params): void
{
    if($params === null) {
        //This expression will always be false. I would like to see it in IDE.
    }
}

Not yet implemented, please vote: https://youtrack.jetbrains.com/issue/WI-35508
