PHP下通过exec获得计算机的唯一标识[CPU,网卡 MAC地址]

//获取电脑的CPU信息

function OnlyU(){
$a = ‘‘;
$b = array();
if(function_exists(‘exec‘)){
if(mailto:!@exec( /all",$b)){
return false;
}
}elseif(function_exists(‘system‘)){
ob_start();
if(mailto:!@system( /all")){
return false;
}else{
}
$b = ob_get_contents();
ob_end_clean();
$b = explode("\n",$b);//print_r($b);
array_pop($b);
}else{
return false;
}

$all = sizeof($b);
for($i = 0; $i < $all; $i++){
if(strpos($b[$i],"Description") !== false){
if(strpos($b[$i+1],"Physical Address") !== false){
$c = explode(":",$b[$i+1]);
$a = trim($c[1]);
break;
}
}
} // End for
return empty($a)?false:$a;
} // End function OnlyU


//获取网卡的MAC的地址

function getMAC() {
@exec("ipconfig /all",$array);
for($Tmpa;$Tmpa<count($array);$Tmpa++){
if(eregi("Physical",$array[$Tmpa])){
$mac=explode(":",$array[$Tmpa]);
return $mac[1];
}
}
}
