Can you check - that looks like the error message is right, and the pattern probably isn't what you want.

As you have it in your script, it means "any character that is between any word character to a dot", which doesn't make sense.

If the pattern was instead "[\w\.]" that would mean any word character or a dot.....which is possibly what you meant?

Testing at: https://3v4l.org/66NDo

preg_match('/^[\w\.]+$/', 'admin.general.canViewPrivateUserOptions', $matches);
var_dump($matches);

preg_match('/^[\w-\.]+$/', 'admin.general.canViewPrivateUserOptions', $matches);
var_dump($matches);

preg_match('/^[\\w-\\.]+$/', 'admin.general.canViewPrivateUserOptions', $matches);
var_dump($matches);
