示例1: Circle
$c = new Circle(10);
print " Created circle \$c\n";
$s = new Square(10);
print " Created square \$s\n";
# ----- Access a static member -----
print "\nA total of " . Shape::nshapes() . " shapes were created\n";
# ----- Member data access -----
# Set the location of the object.
# Note: methods in the base class Shape are used since
# x and y are defined there.

print " Circle = (" . $c->x . "," . $c->y . ")\n";
print " Square = (" . $s->x . "," . $s->y . ")\n";
# ----- Call some methods -----
print "\nCall some overloaded methods:\n";

print " overloaded = " . overloaded($o) . "\n";
}
# Need to unset($o) or else we hang on to a reference to the Square object.

# ----- Delete everything -----
print "\nGuess I'll clean up now\n";
# Note: this invokes the virtual destructor

# created by SWIG. In this case, all of our C++ classes
# get converted into function calls.

# ----- Access a static member -----

# by the ShapeContainer.
