And where is your answer to the question?

Anyway...

arp -a outputs here (numbers as "x" for privacy reasons):

somename (xxx.xxx.xxx.xxx) at xx:xx:xx:xx:xx:xx [ether] on eth0

So - using explode() on this line with space as delimiter should return
an array with the following elements:

somename
(xxx.xxx.xxx.xxx)
at
xx:xx:xx:xx:xx:xx
[ether]
on
eth0

Then you can use the fourth element which contains the MAC address.

If you get more than one line of output, the lines have to be split
first of course. Therefore I'd recommend using exec() which will return
the output as an array with one element for each line of output.
