embed on object

I've embedded a flash movie on the site in an object as follows :

echo ("<object width=\"250\" height=\"200\">
<param name=\"movie\" value=\"target.swf\">
<embed src=\"images/swf/target.swf\" width=\"250\" height=\"200\" loop=\"false\"></embed>
</object>");

Now, once this flash file has played, I want the object to kind of disappear and not leave a "box" behind with the latest scene of the movie.

Is there an easy way of doing this?

Not with PHP. You would need to put something in the flash file that calls a javascript function once its done playing to hide it by changing its style properties.
