Is there a PHP equivalent for `public static main(String[] args)` in Java?

Is there a way to program 100% object-oriented in PHP?

What I am trying to accomplish would look something like this:

 <?php
      //index.php
      class Site{
           public static function main(){
                // starts all the processing of the site
           }
      }
 ?>

So that when someone visits the site's index.php the site will start up without having any code outside the class.

Yes I know that I could use __autoload or even spl_autoload_register to handle autoloading of classes but that would still most likely need to be added outside of the class.

I have my doubts that this is possible but I don't know why this wouldn't be possible.
