In this Flash and ActionScript 3 tutorial you can learn how to Use FlashVars and PHP to send a dynamic variable into flash AS3. I show how to use the page that Flash renders to set up FlashVars in and send them into flash. I turn that page into a PHP file by giving a .php extension instead of .html. Then I can write all the PHP I want in it to set up dynamic PHP and ActionScript 3 communication. Your PHP or static HTML file can send variables into flash without having Flash send out a request for the data. FlashVars is placed into three sections of that file if you are using the default page structure that flash renders when you publish.
