// This program demonstrates use of the KML DOM PHP SWIG bindings for
// creating and accessing simple elements and attributes such as
// Feature's <name> and <visibility> and Object's id= as in <Placemark>.
// This example uses the SWIG'd kmldom extension module directly. Because
// SWIG flattens the C++ object structure, you are required to know the
// inheritance hierarchy. For example, to query a Placemark's visibility,
// you have to know that a Placemark is a Feature and the correct function
// call is Feature_has_visibility($placemark).
// SWIG generates a wrapper that does a reasonable job of reflecting the
// source C++ classes into a PHP5 class hierarchy. We recommend you use this
// instead. To see an example of this alternate usage, see
// helloplacemark_wrapper.php
require 'load_kmldom.php'; // Loads the extension module.
