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:


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!
