PHP下通过exec获得计算机的唯一标识[CPU,网卡MAC地址]_PHP教程

//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;$Tmpaif(eregi("Physical",$array[$Tmpa])){ 
$mac=explode(":",$array[$Tmpa]); 
return $mac[1]; 
} 
} 
}
