无法使用ftp_get()下载到硬盘驱动器

Question

是否可以使用PHP的到达下载到我的硬盘驱动器(如我的远程服务器所示)？使用ftp_get()下载是成功的，但是，我从远程服务器下载的文件将被下载到我的php脚本的目录中。我对任何方法都不感到惊讶，但我想知道如何将下载目录更改为硬盘上的特定位置，例如"C:\“驱动器。

下面的代码来自php.net，但这正是我的代码的设置方式：

<?php

// define some variables
$local_file = 'local.rar';
$server_file = 'server.rar';

// set up basic connection
$conn_id = ftp_connect($ftp_server);

// login with username and password
$login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass);

// try to download $server_file and save to $local_file
if (ftp_get($conn_id, $local_file, $server_file, FTP_BINARY)) {
    echo "Successfully written to $local_file\n";
} else {
    echo "There was a problem\n";
}

// close the connection
ftp_close($conn_id);

?>

谢谢你的帮助，

要在本地下载文件，PHP脚本需要发送适当的头，然后回显文件的内容。但是，只有在尚未从PHP脚本(通过echo或其他方式)引发任何其他输出的情况下，才会发生这种情况。此代码应导致浏览器打开文件保存窗口或将其下载到默认位置。

// try to download $server_file and save to $local_file
if (ftp_get($conn_id, $local_file, $server_file, FTP_BINARY)) {

    // Don't echo output here...
    //echo "Successfully written to $local_file\n";

    // You've downloaded the file into `$local_file` on your server. 
    // Now send it to the browser:
    header("Content-type: application/x-rar-compressed");

    // Also helps to send Content-length
    header("Content-length: " . filesize($local_file));

    // Dump out the file contents
    echo file_get_contents($local_file);

    // Delete it from the server
    unlink($local_file);

    // Always exit when you're done
    exit();
} else {
    echo "There was a problem\n";
}
