How would it? Each element in $users have a trailing "\n".

Start from scratch. You have a file with a single user on each line:
tom\n
dick\n
harry\n
You use file() to read into array $users.
You compare as in above.
You add a user by:
$users[] = "NEW_USER\n";
You write out the file as above.
If my logic haven't gone awry somewhere, that's your problem solved!
