Since checkDestinationPath() is declared private, calling it with static will lead to errors in possible sub-classes. You can either use self, or increase the visibility of checkDestinationPath() to at least protected.

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

class YourClass
{
    private static function getTemperature() {
        return "3422 °C";
}

public static function getSomeVariable()
{
    return static::getTemperature();
}

}

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 {
      private static function getTemperature() {
        return "-182 °C";
    }
}

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

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

class YourClass
{
    private static function getTemperature() {
        return "3422 °C";
    }

    public static function getSomeVariable()
    {
        return self::getTemperature();
    }
}
