Get Client MAC And IP Address Using PHP

Before we get started with Get Client MAC And IP Address Using PHP, first, we have to know some general details about Mac and the IP address of the system.

What is a MAC address?

MAC stands for Media Access Control and it is also known as the physical address. Which is associated with every networking device.

It is a 48-bit physical address that is printed on NIC(Network Interface Card) and is globally unique.

What is an IP address?

An IP address is also known as Intenet Protocol and logical address provided by the ISP (Internet service provider),

Which uniquely identifies the system over the internet, but it keeps changing from time to time.

Get Client’s MAC Address Using PHP

Method-1:

<?php
echo GetMACAdd();

function GetMACAdd(){
  ob_start();
  system('getmac');
  $Content = ob_get_contents();
  ob_clean();
  return substr($Content, strpos($Content,'\\')-20, 17);
}
?>

<?php

echo GetMACAdd();

function GetMACAdd(){

ob_start();

system('getmac');

$Content = ob_get_contents();

ob_clean();

return substr($Content, strpos($Content,'\\')-20, 17);

}

Method-2:

<?php

ob_start(); // Turn on output buffering
system('ipconfig /all'); //Execute external program to display output
$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

echo $mac;

?>

<?php

ob_start(); // Turn on output buffering

system('ipconfig /all'); //Execute external program to display output

$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

echo $mac;

Code Highlights:
