Question

我试图在数据库中保存远程用户IP。出于此目的，我已将列创建为int(10) UNSIGNED。

当我尝试这样做时，一切正常，但IP保存为127.0.0.1

$ipaddr = $_SERVER['REMOTE_ADDR'];
$stmt = $pdo->prepare('INSERT INTO comment (body, author, email, date, url, ip) VALUES (:body, :author, :email, NOW(), :url, :ipaddr)');

$stmt->execute(array(
    ':body' => $_POST['k3jZGEeX1k1oo'],
    ':author' => $_POST['k3k0xKicU0eHQ'],
    ':email' => $email,
    'url' => $url,
    'ip' => $ipaddr
));

当我尝试使用INET_ATON时，数据库中没有任何内容。

$ipaddr = $_SERVER['REMOTE_ADDR'];
$stmt = $pdo->prepare('INSERT INTO comment (body, author, email, date, url, ip) VALUES (:body, :author, :email, NOW(), :url, :INET_ATON(ipaddr))');

$stmt->execute(array(
        ':body' => $_POST['k3jZGEeX1k1oo'],
        ':author' => $_POST['k3k0xKicU0eHQ'],
        ':email' => $email,
        'url' => $url,
        'ip' => $ipaddr
));

请注意:INET_ATON(ipaddr)。我如何用准备好的陈述来做到这一点？

正如@ Fred-ii-所说，你应该检查错误。我也可以推荐this solution并构建php函数ip2long。在你的情况下将是

$ipaddr = $_SERVER['REMOTE_ADDR'];
$ip = sprintf("%u", ip2long($ipaddr));

$stmt = $pdo->prepare('INSERT INTO comment (body, author, email, date, url, ip) VALUES (:body, :author, :email, NOW(), :url, :ip)');

$stmt->execute(array(
    ':body' => $_POST['k3jZGEeX1k1oo'],
    ':author' => $_POST['k3k0xKicU0eHQ'],
    ':email' => $email,
    ':url' => $url,
    ':ip' => $ip
));

要选择并查看实际的IP，您可以在查询中使用INET_NTOA（同样来自@ Fred-ii-评论）。
