I need to secure data being sent from my Flash games to my PHP file.
Previously I was simply using a secret authorisation code, which was sent from the Flash file, and then checked against the code specified in the PHP file. However, using flasm to disassemble the swf I see it is very easy to ascertain this code - or indeed any secret checks that come from within the Flash file.
How can I then make this data secure?

I want to connect my fla file with mysql database via php.
How can I do that, please help me with an example.

I have tried lots of tutorials but I NEVER can get it to work. So, How can I make a Flash guestbook without using php or mysql?
