Note that what you have will check if there's that 5-4 somewhere inside $input. As in it will quite happily match with

$input = "a bunch of stuff then 12345-6789 and then more stuff";
If you want to make sure $input has only that 5-4 then you need ^ and $ anchors to mark the beginning and end of the string.
