 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
 foreach(preg_split("/(\r?\n)/", $mycom) as $line){
  if(strstr($line, 'Physical Address'))
  {
   $Mac[]= substr($line,39,18);
  }
 }
 return $Mac;
}
