SWFMovie::add — Adds any type of data to a movie
此函数是实验性的。此函数的表象，包括名称及其相关文档都可能在未来的 PHP 发布版本中未通知就被修改。使用本函数风险自担 。
Adds an SWF object instance to the current movie.
For displayable types (shape, text, button, sprite), this returns an SWFDisplayItem, a handle to the object in a display list. Thus, you can add the same shape to a movie multiple times and get separate handles back for each separate instance.
