Question

我有一个循环，我遍历许多域并且我ping主题：循环如下：

foreach ($rows[1] as $domains){
$domain='www.'.$domains;
$output = shell_exec('ping -c1 '.$domain.'');
echo "<pre>$output</pre>";

}

我的问题：是否可以为每个循环域写出结果IP地址？

Answer 1

当然，只需使用gethostbyname（PHP文档）。例如：

foreach ($rows[1] as $domains){
   $domain='www.'.$domains;
   $output = shell_exec('ping -c1 '.$domain.'');
   echo "<pre>$output</pre>";
   echo gethostbyname($domain);
}

Answer 2

试试这个

foreach ($rows[1] as $domains){
    $domain='www.'.$domains;
    $ip = gethostbyname($domain);
    echo $domain.','.$ip.'\n';
}

//OUPUT HEADERS
header("Pragma: public");
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Cache-Control: private",false);
header("Content-Type: application/octet-stream");
header("Content-Disposition: attachment; filename=domains.csv;" );
header("Content-Transfer-Encoding: binary");

ping域并在csv文件中写出ip
