php - ftp_get

I'm using the function ftp_get() in my ftp access. The problem is that I can't tell if the file is downloaded or not. How can I resolve this problem? The page that has this function gets the vars from an url ( ex. www.mysite.com/hello.php?name=rui&pass=superfly) Another problem to concern is the fact that the var containing the password is printed in the url. Is there a funcion that incripts this? Thank's, Rui
