How to get MAC Address of all Devices in my Network using PHP ?


MAC Address

According to Wikipedia, a media access control address (MAC address) of a device is a unique identifier assigned to a network interface controller (NIC). For communications within a network segment, it is used as a network address for most IEEE 802 network technologies, including Ethernet, Wi-Fi, and Bluetooth.

Address Resolution Protocol (ARP)

The Address Resolution Protocol (ARP) is a communication protocol used for discovering the link layer address, such as a MAC address, associated with a given internet layer address, typically an IPv4 address. This mapping is a critical function in the Internet protocol suite.


$arp=`arp -a`;
$lines=explode("\n", $arp);
$devices = array();
foreach($lines as $line){
    $cols=preg_split('/\s+/', trim($line));
    if(isset($cols[2]) && $cols[2]=='dynamic'){
    	$temp = array();
    	$temp['ip'] = $cols[0];
    	$temp['mac'] = $cols[1];
    	$devices[] = $temp;

          <?php foreach($devices as $device){?>
              <td><?php echo $device['ip'];?></td>
              <td><?php echo $device['mac'];?></td>
