SWFDisplayItem::setDepth — Sets z-order
$depth
)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 。
swfdisplayitem::setdepth() sets the object's
z-order to depth. Depth defaults to the
order in which instances are created (by adding a shape/text to
a movie)- newer ones are on top of older ones. If two objects are
given the same depth, only the later-defined one can be moved.
The object may be a swfshape(), a swfbutton(), a swftext() or a swfsprite() object. It must have been added using the swfmovie::add().
