Php: three methods for obtaining the mac address of a local machine-PHP source code

Ec (2); & nbsp; copy the code classgetmacaddr {& nbsp; var $ return_arrayarray (); returns a string array with a mac address & nbsp; v script ec (2); script

The Code is as follows:

Class getmacaddr { Var $ return_array = array (); // returns a string array 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 2

The Code is as follows:

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:

Int getalllocaladaptermacaddr (std: list > & Mac) { 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 pstutorial z_name [30]; } Adapter; // Reset the lan adapter so that we can begin querying it 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 it in standard, // Colon-delimited form. If (netbios (& ncb) = 0) { Std: vector V6; V6.resize (6 ); For (int I = 0; I <6; I ++) V6 [I] = adapter. adapt. adapter_address [I]; If (v6 [0] = 0) { Std: list >:: 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; }
