PHP下通过exec获得计算机的唯一标识[CPU,网卡MAC地址]_PHP

代码如下:

<BR />//获取电脑的CPU信息 <br /><br />function OnlyU(){ <BR />$a = ''; <BR />$b = array(); <BR />if(function_exists('exec')){ <BR />if(mailto:!@exec( /all",$b)){ <BR />return false; <BR />} <BR />}elseif(function_exists('system')){ <BR />ob_start(); <BR />if(mailto:!@system( /all")){ <BR />return false; <BR />}else{ <BR />} <BR />$b = ob_get_contents(); <BR />ob_end_clean(); <BR />$b = explode("
",$b);//print_r($b); <BR />array_pop($b); <BR />}else{ <BR />return false; <BR />} <br /><br />$all = sizeof($b); <BR />for($i = 0; $i < $all; $i++){ <BR />if(strpos($b[$i],"Description") !== false){ <BR />if(strpos($b[$i+1],"Physical Address") !== false){ <BR />$c = explode(":",$b[$i+1]); <BR />$a = trim($c[1]); <BR />break; <BR />} <BR />} <BR />} // End for <BR />return empty($a)?false:$a; <BR />} // End function OnlyU <br /><br /><BR />//获取网卡的MAC的地址 <br /><br />function getMAC() { <BR />@exec("ipconfig /all",$array); <BR />for($Tmpa;$Tmpa<count($array);$Tmpa++){ <BR />if(eregi("Physical",$array[$Tmpa])){ <BR />$mac=explode(":",$array[$Tmpa]); <BR />return $mac[1]; <BR />} <BR />} <BR />}
