检索用户的 IP 地址并将其存储在数据库表中？答案

【问题标题】：Retrieve users' IP addresses and store them in a database table?检索用户的 IP 地址并将其存储在数据库表中？
【发布时间】：2013-04-25 16:38:18
【问题描述】：

我有一个 MySQL 查询，它将表单的内容插入到我的数据库中。

除了插入这些值之外，我还想发现并插入用户 IP 地址。这是为了网站的保护。这样，如果用户不断发布有害内容，他们的 ip 就会被屏蔽。

这是我的脚本。我正在尝试使用" . $_SERVER['REMOTE_ADDR'] . "，但它对我不起作用。有人可以告诉我这样做的方法吗？

我正在尝试将 IP 存储在我的表中名为“ip”的列中（int(10) 属性：UNSIGNED NULL:No Default:None）

更新：

当我将 'ip' 列更改为 VARCHAR(48) 时，我会在列中打印此内容，而不是完整的 IP：::1

<?php

ob_start();

// check if the review form has been sent
if(isset($_POST['review_content'])) {
    if(isset($_POST['review_recipient'])) {
        $content = $_POST['review_content'];
        $review_recipient = $_POST['review_recipient'];

        //We remove slashes depending on the configuration
        if(get_magic_quotes_gpc()) {
                $content = stripslashes($content);
                $review_recipient = stripslashes($review_recipient);
        }

        $regex = "/(https?:\/\/)?([\da-z\.-]+)\.([a-z\.]{2,6})([\/\w\.-]*)*\/?/";
        $replacement = "[blocked url]";

        $regex2 = "/(.*)\b(BLOCKED WORDS GO HERE!!!!)\b(.*)/";
$replacement2 = "[blocked content]<br/><br/>This content was blocked because it was deemed offensive or inappropriate.";

$replacement3 = "[blocked username]";


        $review_recipient = preg_replace(Array($regex, $regex2),Array($replacement, $replacement3),$_POST['review_recipient']);
        //$profile_id = intval($_POST['profile_id']); //dont know how you get this
        $content = preg_replace(Array($regex, $regex2),Array($replacement, $replacement2),$_POST['review_content']);


        //We check if all the fields are filled
        if($_POST['review_content']!='') {
            if($_POST['review_recipient']!='') {

                $sql = "INSERT INTO ptb_reviews (id, from_user_id, from_guest, ip, to_user_id, content) VALUES (NULL, '-1', '".$review_recipient."', '" . $_SERVER['REMOTE_ADDR'] . "', '".$profile_id."', '".$content."');";
                mysql_query($sql, $connection);

                $_SESSION['message']="<div class=\"infobox-review-sent\"><strong>Thank You</strong> - Your review has been sent and is awaiting approval.</div><div class=\"infobox-close4\"></div>";

                header("Location: {$_SERVER['HTTP_REFERER']}");
            }
        }

    }

} } }

?>

【问题讨论】：

您遇到什么错误？另外，请使用 PDO mysql_query 命令已弃用。
$_SERVER['REMOTE_ADDR'] 是一个类似192.168.55.7 的字符串。这对你来说看起来像一个整数吗？
我没有收到任何错误，只是没有将任何内容插入到表中。 @Barmar，所以如果我将 ip 列更改为 varchar(48) 会起作用吗？
你甚至没有检查错误，你怎么知道？您需要检查mysql_query 的返回值，如果为false，则打印mysql_error()。您可以使用ip2long() 将IP 地址转换为整数，也可以将其存储在char(15) 中。
::1 是localhost 的 IPv6 地址。

【解决方案1】：

使用INET_ATON进行存储，检索时使用INET_NTOA：

<?php

ob_start();

// check if the review form has been sent
if(isset($_POST['review_content'])) {
    if(isset($_POST['review_recipient'])) {
        $content = $_POST['review_content'];
        $review_recipient = $_POST['review_recipient'];

        //We remove slashes depending on the configuration
        if(get_magic_quotes_gpc()) {
                $content = stripslashes($content);
                $review_recipient = stripslashes($review_recipient);
        }

        $regex = "/(https?:\/\/)?([\da-z\.-]+)\.([a-z\.]{2,6})([\/\w\.-]*)*\/?/";
        $replacement = "[blocked url]";

        $regex2 = "/(.*)\b(BLOCKED WORDS GO HERE!!!!)\b(.*)/";
$replacement2 = "[blocked content]<br/><br/>This content was blocked because it was deemed offensive or inappropriate.";

$replacement3 = "[blocked username]";


        $review_recipient = preg_replace(Array($regex, $regex2),Array($replacement, $replacement3),$_POST['review_recipient']);
        //$profile_id = intval($_POST['profile_id']); //dont know how you get this
        $content = preg_replace(Array($regex, $regex2),Array($replacement, $replacement2),$_POST['review_content']);


        //We check if all the fields are filled
        if($_POST['review_content']!='') {
            if($_POST['review_recipient']!='') {

                $sql = "INSERT INTO ptb_reviews (id, from_user_id, from_guest, ip, to_user_id, content) VALUES (NULL, '-1', '".$review_recipient."', 'INET_ATON(" . $_SERVER['REMOTE_ADDR'] . "'), '".$profile_id."', '".$content."');";
                mysql_query($sql, $connection);

                $_SESSION['message']="<div class=\"infobox-review-sent\"><strong>Thank You</strong> - Your review has been sent and is awaiting approval.</div><div class=\"infobox-close4\"></div>";

                header("Location: {$_SERVER['HTTP_REFERER']}");
            }
        }

    }

} } }

?>

但请注意，如果您使用的是 IPv6，这将不起作用。如果是这种情况，则需要 INET6_ATON 和 INET6_NTOA 函数。
