You can get MAC Address or Physical Address using this code 

$d = explode('Physical Address. . . . . . . . .',shell_exec ("ipconfig/all"));  
$d1 = explode(':',$d[1]);  
$d2 = explode(' ',$d1[1]);  
return $d2[1];

I used explode many time because shell_exec ("ipconfig/all") return complete detail of all network. so you have to split one by one. when you run this code then you will get
your MAC Address 00-##-##-CV-12 //this is fake address for show only.

You can use the following solution to solve your problem:

$mac='UNKNOWN';
foreach(explode("\n",str_replace(' ','',trim(`getmac`,"\n"))) as $i)
if(strpos($i,'Tcpip')>-1){$mac=substr($i,0,17);break;}
echo $mac;

Perhaps getting the Mac address is not the best approach for verifying a client's machine over the internet. Consider using a token instead which is stored in the client's browser by an administrator's login.

Therefore the client can only have this token if the administrator grants it to them through their browser. If the token is not present or valid then the client's machine is invalid.

too late to answer but here is my approach since no one mentioned this here:
why not a client side solution ?
a javascript implementation to store the mac in a cookie (you can encrypt it before that)
then each request must include that cookie name, else it will be rejected.
to make this even more fun you can make a server side verification
from the mac address you get the manifacturer (there are plenty of free APIs for this)
then compare it with the user_agent value to see if there was some sort of manipulation:
a mac address of HP + a user agent of Safari = reject request.

We can get MAC address in Ubuntu by this ways in php 

$ipconfig =   shell_exec ("ifconfig -a | grep -Po 'HWaddr \K.*$'");  
    // display mac address   
 echo $ipconfig;

Getting MAC Address Using PHP: (Tested in Ubuntu 18.04) - 2020 Update

Here's the Code:

<?php
    $mac = shell_exec("ip link | awk '{print $2}'");
    preg_match_all('/([a-z0-9]+):\s+((?:[0-9a-f]{2}:){5}[0-9a-f]{2})/i', $mac, $matches);
    $output = array_combine($matches[1], $matches[2]);
    $mac_address_values =  json_encode($output, JSON_PRETTY_PRINT);   
    echo $mac_address_values
?>

Output:

{
    "lo": "00:00:00:00:00:00",
    "enp0s25": "00:21:cc:d4:2a:23",
    "wlp3s0": "84:3a:4b:03:3c:3a",
    "wwp0s20u4": "7a:e3:2a:de:66:09"
}

This one works for me:

<?php
  
// PHP code to get the MAC address of Server
$MAC = exec('getmac');
  
// Storing 'getmac' value in $MAC
$MAC = strtok($MAC, ' ');
  
// Updating $MAC value using strtok function, 
// strtok is used to split the string into tokens
// split character of strtok is defined as a space
// because getmac returns transport name after
// MAC address   
echo "MAC address of Server is: $MAC";
?>
