I'm pretty new to php, but I'm trying to build a page that uses Flash to show / choose documents, and then html to show them in an iFrame below (because Flash can't show things like powerpoint). I've managed to send information from Flash to a php file, but I can't get the iFrame to show the document that I chose.

Is there a way for php to tell an iFrame to refresh with the new url it creates when it gets information from Flash?
