Flash-PHP Socket Connection

Hi everybody I'm working on a site that will be based on Flash, PHP and MySQL. PHP will work as a middleware for Flash and MySQL. My problem is communication between Flash and PHP. I'm really out looking for using the socket functions in PHP and Flash to make fast connection. I have googled for almost an hour now, and I can't seem to find any interesting. The only info I find, is about sending data between Flash and PHP with HTTP GET or HTTP POST. So if anybody has some general information on this or a link to a tutorial on the subject, I would like to get those resources. Thanks a lot Eric
