Have you echoed the two defined variables within the function to make sure they are retrieving the correct strings?

Never mind. I changed abit and eventually it worked

define('REMOTE_VERSION', 'http://domain.com/version.txt');

// this is the version of the deployed script
$current_version = "1.0.0";
$remoteVersion = trim(file_get_contents(REMOTE_VERSION));

if($remoteVersion == $current_version) {
    // yes
} elseif($remoteversion < $current_version) {
    // no
}

?>

Unfortunately, that isn't going to do what you need. Because comparison will only work to the first decimal point. If you plan to do it that way, convert each period to a zero.
