ftp登錄並使用PHP放置文件

Question

我是PHP新手，所以請放輕松！ 我想做的是以下幾點：

• 用戶轉到html登錄頁面並輸入其詳細信息（這些實際上是其unix的長期輸入）
• 如果這些是正確的，則要求用戶輸入一些信息，然后按提交
• 執行此操作時，將創建具有今天日期的文件，並且內容由用戶選擇。
• 該文件通過ftp傳送到用戶unix帳戶的根目錄，我應該遵循什么過程進行？

到目前為止，我的PHP看起來像這樣（但是不起作用）

<?php

$ftp_server = '192.168.103.11'; //actual domain is listed here.
$ftp_username = $_POST['username'];
$ftp_password = $_POST['password'];
$location = "ftp://$ftp_username:$ftp_password@$ftp_server";
$dest = '/home/detica/mjm/'
$source = '/var/www/html/test.txt'
$mode = 'FTP_ASCII'

$ftp_connect_id = ftp_connect($ftp_server);
$ftp_login = ftp_login($ftp_connect_id, $ftp_username, $ftp_password);
if (! $ftp_connect_id || ! $ftp_login)
{
echo "Unable to connect to $ftp_server";
exit;
} else {
header("Location: $location");
echo "Connected to host $ftp_server";

$upload = ftp_put($ftp_connect_id, $dest, $source, $mode);

if (!$upload) { echo 'FTP upload failed!'; }

ftp_close(ftp_connect_id);
}
ftp_close($ftp_connect_id);
?>

我很快就把這些東西放在一起，請您把它弄糟，請病假；希望它能對您有所幫助。
