PHP - Flash changes .php files, possible?


Im currently making like a “web-game” in flash, and need alot of uniques variables. So my big question is:

Can flash edit a php file?
Like add a variable
(like the var name “name+”"+namelogin" or “gold+”"+namelogin")
so all can have uniques variables, each for each account.

I have only seen tutorials that swf files take information from a php database.
Now, can flash change the database?
