How does php obtain the MAC address of the NIC (Windows and LINUX are supported)
For example, php obtains the physical address of the NIC, that is, the mac address.
/** - Obtain the MAC address of the NIC. Currently, Windows/LINUX are supported.
- Obtain the physical (MAC) address of the machine Nic
- **/
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;
- } Bbs.it-home.org
} - 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"]. "\ system32 \ ipconfig.exe ";

Function forLinux (){ - @ Exec ("ifconfig-a", $ this-> return_array );
- Return $ this-> return_array;
- }
} - // Method usage
- $ Mac = new GetMacAddr (PHP_ OS );
- Echo $ mac-> mac_addr; // The actual MAC address of the machine. comment out the address.
