typedef byte SkNetMAC[6];

bool FkNetGetMacA( CkStr SA, SkNetMAC &MAC )
{
if( SA.IsEmpty() ) return(false);

#if 1 // get local or remote MAC given an IP using ARP (Win2K+)

ulong   rc = 0,
        ml = sizeof(MAC);
IPAddr  ip = inet\_addr( SA.PtrSafe(0) );

rc = ::SendARP(ip, 0, (ulong\*)&MAC, &ml);

#else // get local MAC associated with IP by querying adapter info (Win*)

ulong             rc = 0,
                  al = 0;
IP\_ADAPTER\_INFO  \*ai = NULL,
                 \*ac = NULL;

if( rc != ERROR\_BUFFER\_OVERFLOW )  return(false);

ai = (IP\_ADAPTER\_INFO\*)ckMemTemp.Calloc(al);
if( !ai )  return(false);

rc = ::GetAdaptersInfo(ai, &al);
if( rc != ERROR\_SUCCESS )  goto e\_FkNetGetMacA;

// there can be a many to one relationship between
// ip's and addapters - search adapters for matching IP
for( ac = ai;  ac;  ac = ac->Next ) {
	for( ip = &ac->IpAddressList;  ip;  ip = ip->Next ) {

e\_FkNetGetMacA:
ckMemTemp.Free(ai);

#endif

return(true);

Am looking for PHP code to get the Mac address of a machine and I think you got the answer.
