php - PHP ftp_login 警告“您将在 10 分钟不活动后断开连接”

问题描述

我写了这个脚本来连接一个 FTP 服务器

$ftp_server = 'ftp.xxx.com';
$ftp_user_name = 'myusername';
$ftp_user_pass = 'mypassword';

$conn_id = ftp_connect($ftp_server,21);
if ($conn_id)
{
    echo("Connected to FTP<br><br>");
}
else
{
    echo("Connection error<br>");
}
$login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass);
var_dump($login_result);

我正确地看到“已连接到服务器 FTP”，但出现此错误后

警告：ftp_login()：您将在 10 分钟不活动后断开连接。

我没有激活防火墙。

我可以使用 FileZilla 登录：

解决方案

当您使用 FileZilla 登录时，它使用加密的 FTPS 连接。

要在 PHP 中做同样的事情，请使用ftp_ssl_connect, 而不是ftp_connect.
