What about php linking whith f plyer 8?

Hi guys !!!
i recently test an app made with flash 6 on the flash player 8 :
The animation had to load some data in an Mysql database through an easyphp server.
It works finely with flash player 6 and 7 but when i us flash 8 message box appears telling the user about the danger of connecting and getting data from an unknown source (the server…) and asking him to confirm the connection.
I am almost sure that the users will take this advice in consideration and will cancel the connection, stopping the animation.
What can i do to avoid this message ?
i work with mozilla firefox 1.0 caus the player was installed on it .
tnax for ya help !!! :hangover:
