Question

我尝试了几种在FTP服务器上传文件的方法，但我失败了。

这里我粘贴我的服务器代码（php）来接受设备中的文件，请提供与该服务器代码对应的android代码。

<?php
error_reporting(0);
include("dbconfig.php");
$msg = '';
$status = 1;
$overwrite = 1;
/*echo "<pre>";
print_r($_POST);
echo "</pre>";*/

/*echo "<pre>";
print_r($_FILES);
echo "</pre>";*/
if(trim($_POST['userid'])!='')
{   
    $userid = trim($_POST['userid']);
    $overwrite = trim($_POST['overwrite']);
    if($overwrite == 0)
    {
        $selfilesqry = mysql_query("SELECT filepath FROM userfiles WHERE userid = 1 AND status=1");
        while($row = mysql_fetch_array($selfilesqry))
        {
            $selfiles[] = $row['filepath'];
        }

    }
/*  echo "<pre>";
    print_r($selfiles);
    echo "</pre>";*/
    $host = '97.***.****';
    $usr = '*****************8';
    $pwd = '**********************';

    $paths = '/mobbisys/cloudbin/data';
    //$paths = '/php_projects/mahesh/ftpupload/data';

    // connect to FTP server (port 21)
    $conn_id = ftp_connect($host, 21) or die ("Cannot connect to host");

    // send access parameters
    ftp_login($conn_id, $usr, $pwd) or die("Cannot login");

    for($i=0; $i<count($_FILES['txtfile']['name']); $i++)
    {   
        if($_FILES['txtfile']['name'][$i]!='')
        {
            $type = explode('/',$_FILES['txtfile']['type'][$i]);
            $filetype = $type[0];           
            if($filetype == 'audio')
            {

Answer 1

如果要插入

，则必须包含 move_uploaded_file 功能

语法：move_uploaded_file（string $ filename，string $ destination）

示例：move_uploaded_file($_FILES['uploadedfile']['tmp_name'], "./upload/".$_FILES["uploadedfile"]["name"]);

Answer 2

这是糟糕的代码。为什么不在没有服务器端脚本的情况下通过ftp从android设备上传文件？ see here
