Three ways to get native MAC addresses from PHP

The code is as follows

Copy Code

Class Getmacaddr { var $return _array = Array (); Returns an array of strings with a MAC address var $mac _addr; function getmacaddr ($os _type) { Switch (Strtolower ($os _type)) { Case "Linux": $this->forlinux (); Break Case "Solaris": Break Case "UNIX": Break Case "AIX": Break Default $this->forwindows (); Break } $temp _array = Array (); foreach ($this->return_array as $value) { if (Preg_match ("/[0-9a-f][0-9a-f][:-]". " [0-9a-f] [0-9a-f] [:-]"." [0-9a-f] [0-9a-f] [:-]"." [0-9a-f] [0-9a-f] [:-]"." [0-9a-f] [0-9a-f] [:-]"." [0-9a-f] [0-9a-f]/i ", $value, $temp _array)) { $this->mac_addr = $temp _array[0]; Break } } unset ($temp _array); return $this->mac_addr; } function Forwindows () { @exec ("Ipconfig/all", $this->return_array); if ($this->return_array) return $this->return_array; else{ $ipconfig = $_server["windir"]. " System32ipconfig.exe "; if (Is_file ($ipconfig)) @exec ($ipconfig. "/all", $this->return_array); Else @exec ($_server["windir"]. " Systemipconfig.exe/all ", $this->return_array); return $this->return_array; } } function Forlinux () { @exec ("Ifconfig-a", $this->return_array); return $this->return_array; } } ?> ? $mac = new Getmacaddr (php_os); Echo $mac->mac_addr;

Method Two

The code is as follows

Copy Code

Qstring Getlocalmac () { int Sock_mac; struct Ifreq Ifr_mac; Char mac_addr[30]; Sock_mac = socket (af_inet, sock_stream, 0); if (Sock_mac = = 1) { Perror ("Create socket Falise...mac"); Return ""; } memset (&ifr_mac,0,sizeof (IFR_MAC)); strncpy (Ifr_mac.ifr_name, "eth0", sizeof (Ifr_mac.ifr_name)-1); if ((IOCTL (Sock_mac, SIOCGIFHWADDR, &ifr_mac)) < 0) { printf ("Mac ioctl error"); Return ""; } sprintf (mac_addr, "%02x%02x%02x%02x%02x%02x"), (unsigned char) ifr_mac.ifr_hwaddr.sa_data[0], (unsigned char) ifr_mac.ifr_hwaddr.sa_data[1], (unsigned char) ifr_mac.ifr_hwaddr.sa_data[2], (unsigned char) ifr_mac.ifr_hwaddr.sa_data[3], (unsigned char) ifr_mac.ifr_hwaddr.sa_data[4], (unsigned char) ifr_mac.ifr_hwaddr.sa_data[5]); printf ("Local mac:%s", mac_addr); Close (SOCK_MAC); return qstring (MAC_ADDR); }

Implemented in C

The code is as follows

Copy Code

int getalllocaladaptermacaddr (std::list<std::vector<unsigned char> >& mac) { NCB NCB; Lana_enum adapterlist; memset (&NCB, 0, sizeof (NCB)); Ncb.ncb_command = Ncbenum; Ncb.ncb_buffer = (unsigned char *) &adapterlist; ncb.ncb_length = sizeof (adapterlist); NetBIOS (&NCB); Mac.resize (0); for (int i = 0; i < adapterlist.length; ++i) { struct ASTAT { Adapter_status adapt; Name_buffer PS Tutorial z_name[30]; } adapter; Reset the LAN adapter so we can begin querying it NCB NCB; memset (&NCB, 0, sizeof (NCB)); Ncb.ncb_command = Ncbreset; Ncb.ncb_lana_num = Adapterlist.lana[i]; if (NetBIOS (&NCB)!= Nrc_goodret) Continue Prepare to get the adapter status block memset (&NCB, 0, sizeof (NCB)); Ncb.ncb_command = Ncbastat; Ncb.ncb_lana_num = adapterlist.lana[I]; strcpy ((char *) ncb.ncb_callname, "*"); memset (&adapter, 0, sizeof (adapter)); Ncb.ncb_buffer = (unsigned char *) &adapter; Ncb.ncb_length = sizeof (adapter); Get the adapter's info and, if this works, return to it in standard, colon-delimited form. if (NetBIOS (&NCB) = = 0) { std::vector<unsigned char> V6; V6.resize (6); for (int i=0; i<6; i++) V6[i] = adapter.adapt.adapter_address[i]; if (v6[0] = = 0) { std::list<std::vector<unsigned char> >::iterator i = Mac.begin (); for (; I!=mac.end (); i++) if (*i = = V6) Break if (I==mac.end ()) Mac.push_back (V6); } } Else Break } return 0; }
