Help required on FLash

I am trying to call functions in flash from javascript or php or xml. I cannot change any files, I can just call the api functions. and am not sure on how to do that. I tried to look into different options as listed on the google search, but, found that none could be implemented.

Can anyone help me out on this, on how to acheive it?

I am new to this type of work. I had worked on different projects, but flash is something new. I am aware of action script alone, but not this combination.

Please help or mail me at kiranvnv at gmail with details
