ARP is a root-command... =]
Ok, maybe it's because i've builded my own Linux, and didn't wanted to
have any security, but /sbin/arp has chmod value 755 on my system, and
so, i can execute it with any user.

Hum... Not at all... You need to enter the root password... How can you do
that?
sudo sounds a little better... But... How about security?
Hmm, that would mean that you have to store your root password in your
PHP script ... I don't prefer that, maybe you could use it on a
development server, but don't use it on production server ;)

And with a shell-script outputting the MAC to a .txt temp file, reading it
from the PHP script?
BTW, have a look at suPHP [1]... =]
[1] - http://www.howtoforge.com/suphp_debian_etch_ispconfig
That's really a big job to install :(
