Yeah, although perhaps not very nicely.  It escapes me exactly what layer
DHCP operates at (it must be frame/link layer right?).  If this is the case,
then you'll have problems; PHP doesn't like binary, and it doesn't like raw
sockets; although, you could use libnet
(http://www.packetfactory.net/libnet/) maybe.  If all you need are TCP or UDP
packets, then you're golden; just use the socket extension, which while
called experimental, has worked well enough for me.
