ob_start(); // Turn on output buffering
$sistem = 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 = "Fiziksel";
$pmac = strpos($mycom, $findme); // Find the position of Physical text
$mac=substr($mycom,($pmac+36),17); // Get Physical Address

echo $mac;
if($sistem == false){ echo "hata"; }
?>
