My reply is above - if you bothered to read (which you obviously
didn't). Additionally, the output of arp -a is also dependent on the
operating system and version of arp. Your way requires much more
processing than a simple preg_match().
And in this case the regex is pretty simple, and parses the output he
wants into a multi-dimensional array in one statement.
