Since $converter is declared private, accessing it with static will lead to errors in possible sub-classes; consider using self, or increasing the visibility of $converter to at least protected.
                                                                                                                                                    

                    
                                            

                            

                            

                                
                                    
                                
                            


                            
Let’s assume you have a class which uses late-static binding:


class YourClass
{
    private static $someVariable;

    public static function getSomeVariable()
    {
        return static::$someVariable;
    }
}





The code above will run fine in your PHP runtime. However, if you now create a
sub-class and call the getSomeVariable() on that sub-class, you will receive
a runtime error:


class YourSubClass extends YourClass { }

YourSubClass::getSomeVariable(); // Will cause an access error.





In the case above, it makes sense to update SomeClass to use self instead:


class SomeClass
{
    private static $someVariable;

    public static function getSomeVariable()
    {
        return self::$someVariable; // self works fine with private.
    }
}
