PHP 5.2 Equivalent to Late Static Binding (new static)?

Question

I am trying to make a script that is built for php 5.3 work on a php 5.2 server. The script uses a lot of late static binding like:

return new static($options);

What is the equivalent to this in php 5.2? would it be new self somehow? Or is it not possible to achieve the same effect...

Thanks

EDIT:

Here is a related question New self vs. new static

Juts trying to wrap my head around this late static binding stuff...

There's no equivalent I'm afraid, late static binding was only introduced in PHP 5.3. — Robin, Mar 04 '11 at 18:49
Like @Robin said, there is no equivalent. Maybe get_class() can help you to achieve a similar result? — noun, Aug 18 '14 at 16:49

I think the only way is to pass by a protected static method that build your singleton and a public static method that defines the class to use. You can "emulate" it by using the get_class function over $this

class ParentClass{
    protected static function getInstance2($className){
         //some stuffs here
         return new $className();
    }
    public static function getInstance(){
        return self::getInstance2(get_class(self));
    }
}
class ChildClass extends ParentClass{
    public static function getInstance(){
        return self::getInstance2(get_class(self));
    }
}
