$ip=@$_POST['ip'];
$port=array(21,80,135,443,445,3306,3389,39000);
$time=4;
exec("ping $ip -n $time",$info);
//执行ping命令
if(count($info)>10){
foreach($port as $key=>$value){
$fp=@fsockopen($ip,$value,$errno,$errstr,30);
//打开一个网络连接
$result=$fp?'<span>open<span>':'close';
echo "<table><tr><td>port</td><td>statue</td>";
echo "<td>".$value."<td/><td>".$result."<td/></tr></table>";
