Get the client mac address:

 
@exec("arp -a",$array); // implement arp -a Command, result to array $array in  
foreach($array as $value){ 
// Place matching results in an array $mac_array 
if(strpos($value,$_SERVER["REMOTE_ADDR"]) && preg_match("/(:?[0-9A-F]{2}[:-]){5}[0-9A-F]{2}/i",$value,$mac_array)){ 
$mac = $mac_array[0]; 
break; 
} 
} 
echo $mac; 

Note: mac acquired by the client cannot be tested locally and can only be output if accessed by another computer
