[PHP] "Remove this unused local variable" using "extract".

[li...@nitsnets.com]

Extracted vars are detected as unused variables:

class MyClass 

{
    function response(array $vars)
    {
        extract($vars);
        return sprintf('Hello, %s welcome to %s', $user->name, $site->name);
    }
}

$user and $site return "Remove this unused local variable" error.
