MongoId::__set_state

This function is only used by PHP internally, it shouldn't need to ever be called by the user.

It is identical to the function:

<?php

public static function __set_state($props) {
    return new MongoId("000000000000000000000000");
}

?>

Theoretically, an array of properties used to create the new id. However, as MongoId instances have no properties, this is not used.

A new id with the value "000000000000000000000000".
