That is PHP code, so your chances of getting Flash to display anything with that code are below zero.
what about the URLloader command? Couldn't he refer to php in an external file and have it appear in flash? I know that's not what he is attempting I'm just wondering if it is possible.
If AS3 was being used that could be read from a PHP file, but the mention of "Flash 4 beta" has me doubting URLLoader applies.
