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.
