Actionscript 3 photobooth upload photo with PHP

Morning everyone, in this few days I search for a lot references online and tried to make my first photobooth program with actionscript and PHP, finally I had done the actionscript part, but when I tried to upload my photo which took from actionscript to server via php, the problem had come. I follow and modify from the references and tutorials I found online, but the php part never work, so the last choice for me is look for professional help here, and below is my source code, any professional please tell me where's the problem is, thanks!
