Php obtains the mac address of the server and the mac address of the client. Windows/LINUX is supported.

Get server mac
Copy codeThe Code is as follows:
<? Php
/**
Obtain the MAC address source code of the NIC. Currently, Windows/LINUX systems are supported.
Obtain the physical (MAC) Address of the machine Nic
**/
Class GetmacAddr {
Var $ result = array (); // returns a string array with a MAC address
Var $ macAddr;
/* Construct */
Function _ construct ($ osType ){
Switch (strtolower ($ osType )){

Case "solaris": break;
Case "aix": break;
Case "linux ":{
$ This-> for_linux_ OS ();
} Break;
Default :{
$ This-> for_windows_ OS ();
} Break;
}
$ Temp_array = array ();
Foreach ($ this-> result as $ value ){

}
/* Obtain methods in linux */
Function for_linux_ OS (){
@ Exec ("ifconfig-a", $ this-> result );
Return $ this-> result;

/* Obtain methods in win system */
Function for_windows_ OS (){
@ Exec ("ipconfig/all", $ this-> result );

Return $ this-> result;
} Else {

If (is_file ($ ipconfig )){
@ Exec ($ ipconfig. "/all", $ this-> result );
} Else {
@ Exec ($ _ SERVER ["WINDIR"]. "\ system \ ipconfig.exe/all", $ this-> result );
Return $ this-> result;
}
}
}
}
?>

Obtain the client mac address:
Copy codeThe Code is as follows:
@ Exec ("arp-a", $ array); // run the arp-a command and put the result in the array $ array.
Foreach ($ array as $ value ){
// Put the matching result in the array $ mac_array
If (strpos ($ value, $ _ SERVER ["REMOTE_ADDR"]) & preg_match ("/(:? [0-9A-F] {2} [:-]) {5} [0-9A-F] {2}/I ", $ value, $ mac_array )){
$ Mac = $ mac_array [0];
Break;
}
}
Echo $ mac;

Note: The mac obtained by the client cannot be tested on the local machine. Only access from other computers can be used for output.
