PHP gets the client network card mac physical address

In php programming, by obtaining the user's mac address, you can bind it to the customer's computer, prevent spam registration, etc.
A very simple class. When using it, just print its macAddr attribute directly after instantiation.

Code:

2. class Getmac{
   
3. var $result = array(); // Returns a string array with MAC address
   
4. var $macAddr;
   
5. /*Construction*/
   
6. function __construct($osType){
   
7. switch ( strtolower($osType) ){
   
8. case "unix": break;
   
9. case "solaris": break;
   
10. case "aix": break;
                                                                                                                                          $this->for_windows_os();
11. 
                        $temp_array = array();                                             use using with use using ‐             ‐ ‐ ‐ ‐ ‐ ‐ foreach($this->result as $value){                                                    "."[0-9a-f][0-9a-f][:-]"."[0-9a-f][0-9a-f][:-]"."[0-9a- f][0-9a-f][:-]"."[0-9a-f][0-9a-f][:-]"."[0-9a-f][0-9a-f ]/i",$value,
12. 
                                                                                                                                                                                                                                                                                                                                                                        ​return $this->macAddr;
13. 
    }

    /*Getting method in linux system*/
15. 
    function for_linux_os(){
16. 
    @exec("ifconfig -a", $this->result);
17. 
    return $this->result;
18. 
    }
19. 
    /*Getting method in win system*/
20. 
    function for_windows_os(){
21. 
      @exec("ipconfig /all", $this->result);
22. H if ($ this-& gt; result) {
    
23. Return $ This-& gt; Result;}} Else {

27. $getMac = new Getmac(PHP_OS);
    
28. echo $getMac->macAddr;
