Classic case: Object-oriented Graphing calculator

Classic example: Object-oriented Graphing calculator
In the index.php file, there are
echo New Form ("index.php"); A form is a class that has a construction method inside it.

echo New Result ();
What does this mean, new is not creating an object? So the output object can also ah. What's the name of the object you created?
Report:
The form class is constructed in the following way:
function __construct () {
$this->action= $action;
$this->shape=isset ($_get["action"])? $_get["Action"]: "rect";
}

------Solution--------------------
echo New Form ("index.php"); An instantiated object of the output form, which is an object. Use the Echo output will be error, to use Print_r (); Printing is only a line.
