How to get MAC address of client using PHP?

Question

How can I get MAC Address using PHP or javascript...

Answer 1

<?php

    ob_start();
    system('ipconfig/all');
    $mycom=ob_get_contents(); 
    ob_clean(); 
    $findme = "Physical";
    $pmac = strpos($mycom, $findme); 
    $mac=substr($mycom,($pmac+36),17);

    echo $mac;
?>

This prints the mac address of client machine

Answer 2

First you check your user agent OS Linux or windows or another. Then Your OS Windows Then this code use:

public function win_os(){ 
    ob_start();
    system('ipconfig-a');
    $mycom=ob_get_contents(); // Capture the output into a variable
    ob_clean(); // Clean (erase) the output buffer
    $findme = "Physical";
    $pmac = strpos($mycom, $findme); // Find the position of Physical text
    $mac=substr($mycom,($pmac+36),17); // Get Physical Address

    return $mac;
   }

And your OS Linux Ubuntu or Linux then this code use:

public function unix_os(){
    ob_start();
    system('ifconfig -a');
    $mycom = ob_get_contents(); // Capture the output into a variable
    ob_clean(); // Clean (erase) the output buffer
    $findme = "Physical";
    //Find the position of Physical text 
    $pmac = strpos($mycom, $findme); 
    $mac = substr($mycom, ($pmac + 37), 18);

    return $mac;
    }

This code may be work OS X.

Answer 3

The idea is, using the command cmd ipconfig /all and extract only the address mac.

Which his index $pmac+33.

And the size of mac is 17.

<?php
ob_start();
system('ipconfig /all');
$mycom=ob_get_contents();
ob_clean();
$findme = 'physique';
$pmac = strpos($mycom, $findme);
$mac=substr($mycom,($pmac+33),17);
echo $mac;
?>

Answer 4

Here's a possible way to do it:

$string=exec('getmac');
$mac=substr($string, 0, 17); 
echo $mac;

Answer 5

Use this function to get the client MAC address:

function GetClientMac(){
    $macAddr=false;
    $arp=`arp -n`;
    $lines=explode("\n", $arp);

    foreach($lines as $line){
        $cols=preg_split('/\s+/', trim($line));

        if ($cols[0]==$_SERVER['REMOTE_ADDR']){
            $macAddr=$cols[2];
        }
    }

    return $macAddr;
}

Answer 6

The MAC address (the low-level local network interface address) does not survive hops through IP routers. You can't find the client MAC address from a remote server.

In a local subnet, the MAC addresses are mapped to IP addresses through the ARP system. Interfaces on the local net know how to map IP addresses to MAC addresses. However, when your packets have been routed on the local subnet to (and through) the gateway out to the "real" Internet, the originating MAC address is lost. Simplistically, each subnet-to-subnet hop of your packets involve the same sort of IP-to-MAC mapping for local routing in each subnet.
