for,foreach or while?

First thing I would like to say is that you have to seperate your form names.
Else, since all form names are the same, you get one username.
Second, having the

PHP Code:

if ($username == "")
        { // no point in checking the permission if they dont want to do anything to the confession
            //eval(print_standard_error('invalid_username'));
            // do nothing
        }
        else
        { 


is abit redundant. just say if (!empty($username))

Third, if you pass invite_username as a STR, you will break it as it is an array of usernames.
you must pass it without a datatype.
