class index extends \Sphp\tools\BasicApp{

    private $temp1 = null;

// Application life cycle events with in sequence

    public function onstart(){

        echo "app start";

    }

    public function ontempinit($temp){

        echo " when temp file initialize";

    }

    public function ontempprocess($temp){

        echo "tempfile process";

    }

    public function onready(){

        echo "temp file processed with all components";

    }

    public function page_new(){

       echo "you open in browser " . getThisURL();

    }

    public function page_submit(){
