    public static function getTreeCate ($ category_id, $ = array []) { 

        $ is_parent = D ( 'Article This article was / the Category') -> WHERE ([ "ID" => $ category_id]) -> Find (); 

　　　　　// data present in the array 
        $ array [] = $ is_parent; 

　　　　　// if higher id, continue recursive query section 
        IF ($ is_parent [ "the parent_id"]) { 
            return Self :: getTreeCate ($ is_parent [ 'the parent_id'], $ Array); 
        } 

        
        return $ Array; 

    }

　　

Which it is important to note that define the location of the array, with the recursive function return.
