Well, you will need to parse the output from your arp command to get the
list if IP addresses; a regex function such as preg_match_all will help
you here.
Then you take the output array and use the matching IP addresses to
search your database. The function calls will depend on the database
you're using.
You probably won't find anything like this on the internet; it's not the
type of thing that's commonly done (although there isn't any problem
with it).
BTW - why are you using ob_start()? It just adds overhead to the
process. There are very few reasons you ever need to use it.
