There is a post on the forum at PHPBuilder.com named "Post var and XML Madness" that describes a method of using PHP to parse XML sent to it via the POST method from a Flash movie. After a little experimentation I got it to work, but it requires writing the XML to an external file before parsing. This is Ok until you have about 100+ users at your site, each of whom must have a unique file for the XML operations.

Does anyone know of any simpler methods to manipulate XML data sent to PHP via POST? A solution in which all the xml parsing and data extraction can take place inside a single PHP script? Thanks for your help.
