The variable is available in the file login.php. However, because you attempt to access the variable from within a function (of which you don't supply the variable as a parameter), you need to use the global keyword.

function myf() {
    global $msg; 
    return $msg["CE"];
}

You should take a look at the documentation for variable scope for PHP.
