Question

当用户访问时，我会将IP地址和他们访问的时间保存到一个文本文件中（此文件受保护且不可公开访问）。

PHP是：

 <?php
$file = "ipaddresses.txt";
$timestamp =date('l jS \of F Y h:i:s A');
$f=fopen($file, 'a+');
fwrite($f,$_SERVER['REMOTE_ADDR'], $timestamp."\n");
fclose($f);
?>

我认为我只是将第二个timestamp标记放置在错误的位置，但是即使我节省了其他表格的时间，也似乎无法使用REMOTE ADDR来解决它，只是发布了所有一次输入。

似乎很简单，但我迷路了，因此不胜感激。

EDIT 1:

请查看更新的代码；

<?php
$file = "ipaddresses.txt";
$timestamp =date('l jS \of F Y h:i:s A');
$f=fopen($file, 'a+');
$info = $_SERVER['REMOTE_ADDR'] . $timestamp . "\n";
fwrite($f, $info);
fclose($f);
?>

Answer 1

fwrite() 仅接受两个参数；文件和要写入的信息。

这样，您可能希望将IP和时间戳连接为一个字符串：

fwrite($f, $_SERVER['REMOTE_ADDR'] . $timestamp . "\n");

或者：

$info = $_SERVER['REMOTE_ADDR'] . $timestamp . "\n";
fwrite($f, $info);

Answer 2

<?php
$file = "ipaddresses.txt";
$timestamp =date('l jS \of F Y h:i:s A');
$f=fopen($file, 'a+');
$info = $_SERVER['REMOTE_ADDR'] . $timestamp . "\n";
fwrite($f, $info);
fclose($f);
?>

function getRealIpAddr(){
    if(isset($_SERVER["HTTP_CF_CONNECTING_IP"])){
        $_SERVER['REMOTE_ADDR'] = $_SERVER["HTTP_CF_CONNECTING_IP"];
        $_SERVER['HTTP_CLIENT_IP'] = $_SERVER["HTTP_CF_CONNECTING_IP"];
    }
    $client  = @$_SERVER['HTTP_CLIENT_IP'];
    $forward = @$_SERVER['HTTP_X_FORWARDED_FOR'];
    $remote  = $_SERVER['REMOTE_ADDR'];
    if(filter_var($client, FILTER_VALIDATE_IP)){
        $ip = $client;
    } elseif(filter_var($forward, FILTER_VALIDATE_IP)){
        $ip = $forward;
    } else{
        $ip = $remote;
    }
    return $ip;
}

$Ip_Address = getRealIpAddr();
$Timestamp = date("Y-m-d H:i:s");
$array = array("IP"=>$Ip_Address,"Timestamp"=>$Timestamp);
$myfile = fopen("ipaddresses.txt", "a+") or die("Unable to open file!");
fwrite($myfile, json_encode($array));
fclose($myfile);
