示例1: get_resources_from_source
/**
* Gets the list of included resources as a list of absolute or relative paths of
* resources included in the current item. This allows for a better SCORM export.
* The list will generally include pictures, flash objects, java applets, or any other
* stuff included in the source of the current item. The current item is expected
* to be an HTML file. If it is not, then the function will return and empty list.
* @param string type (one of the Chamilo tools) - optional (otherwise takes the current item's type)
* @param string path (absolute file path) - optional (otherwise takes the current item's path)
* @param int level of recursivity we're in
* @return array List of file paths. An additional field containing 'local' or 'remote' helps determine if the file should be copied into the zip or just linked
