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.

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 ;)
