用PHP上传大文件到FTP [英] Upload large files to FTP with PHP

问题描述

我试图用php上传大文件到一个ftp服务器。我可以上传小文件，但在上传大文件时遇到问题。我查了一下，发现我需要设置upload_max_filesize和post_max_size，将ftp设置为被动模式，并将时间限制设置为从不。我没有设置时间限制的运气，我现在有什么不返回任何错误，但它也没有上传文件。如果你看看 if（！$ upload）{ line在底部，它应该回显一些东西，但是不是。更重要的是，它只是不工作。对于发生了什么问题或者我需要做什么来做这个工作有什么见解？谢谢！

  ini_set（'upload_max_filesize'，'50M'）; 
 ini_set（'post_max_size'，'50M'）; 
 
 $ conn_id = ftp_connect（$ ftp_server）; 
 
 //使用用户名和密码登录
 $ login_result = ftp_login（$ conn_id，$ ftp_user_name，$ ftp_user_pass）; 
 $ b $ //检查连接
 if（（！！conn_id）||（！$ login_result））{
 echoFTP连接失败！ 
 echo试图连接到$ ftp_server用户$ ftp_user_name; 
出口; 
} 
 
 //在
上启用被动模式ftp_pasv（$ conn_id，true）; 
 
 if（$ _ FILES ['upload_file'] ['name']！=''）{
 $ source_file = $ _FILES ['upload_file'] ['tmp_name']; 
 $ destination_file = $ _FILES ['upload_file'] ['name']; 
 
 //上传文件
 $ upload = ftp_put（$ conn_id，$ destination_file，$ source_file，FTP_BINARY）; 
 
 //检查上传状态
 if（！$ upload）{
 echoFTP upload has failed！< br />; 
} else {
 echo上传$ source_file到$ ftp_server作为$ destination_file< br />;

我发现我无法从php页面设置upload_max_filesize值;另外，我似乎无法获得.htaccess的工作：如果我有一个.htaccess文件，它会导致HTTP错误500.此外，我没有访问php.ini。
 
 
如何更改upload_max_filesize值？

我的网页管理员告诉我，我在一个IIS基于Windows的系统，所以.htaccess文件将无法正常工作。有没有办法，我可以影响文件上传大小与web.config？
 
解决方案
从这个网站： http://www.php.net/manual/en/ini.php  
 
'upload_max_filesize'和'post_max_size'
 
 
是类型PHP_INI_PERDIR 
 
 
 
这意味着Entry可以在php.ini，.htaccess或httpd.conf中设置。所以你不能在你的脚本中设置。

个人而言，我想做同样的东西（通过ftp上传大文件）并最终编写一个Java应用程序。为了处理大文件，php并不是最好的方法。网页浏览器并不真的喜欢这个。所以，为了处理大文件，我建议看看其他的选择：（java，swf，javascript，...）
 
 
 
我想试一试当我有一段时间是 http://nodejs.org/  
 
I'm trying to upload large files with php to an ftp server.  I can upload small files, but I'm having trouble uploading larger files.  I have looked it up and found that I need to set upload_max_filesize and post_max_size, set ftp to passive mode, and set time limit to never.  I had no luck with setting the time limit, and what I have now isn't returning any errors, but it is also not uploading the file.  If you look at the if (!$upload) { line at the bottom, it should echo something, but it isn't.  More importantly, it just isn't working.  Any insight as to what is going wrong or what I need to do to make this work?  Thank you!
ini_set('upload_max_filesize', '50M');   
ini_set('post_max_size', '50M');  

$conn_id = ftp_connect($ftp_server);

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

// check connection
if ((!$conn_id) || (!$login_result)) {
        echo "FTP connection has failed!";
        echo "Attempted to connect to $ftp_server for user $ftp_user_name";
        exit;
}

 // turn passive mode on
ftp_pasv($conn_id, true);

if($_FILES['upload_file']['name']!=''){
    $source_file = $_FILES['upload_file']['tmp_name'];
    $destination_file = $_FILES['upload_file']['name']; 

    // upload the file
    $upload = ftp_put($conn_id, $destination_file, $source_file, FTP_BINARY);

    // check upload status
    if (!$upload) {
            echo "FTP upload has failed!<br />";
        } else {
            echo "Uploaded $source_file to $ftp_server as $destination_file<br />";
        }       
}


UPDATE

I've discovered that I cannot set the upload_max_filesize value from the php page; also, I can't seem to get .htaccess to work: if I have an .htaccess file it results in a HTTP Error 500.  Also, I don't have access to php.ini.

How else can I change the upload_max_filesize value?

More Information

My web administrator has told me that I am on an IIS windows-based system, so .htaccess files won't work.  Is there a way that I can affect the file upload size with web.config?
解决方案
From this site: http://www.php.net/manual/en/ini.php

  
'upload_max_filesize' and 'post_max_size'
are of type PHP_INI_PERDIR

which means Entry can be set in "php.ini, .htaccess or httpd.conf". So you can't set it in your script.

--- Edit 2 ---

Personally, I wanted to do the same kind of stuff (upload large files over ftp) and end up writing a java application. For handling large files, php is not really the best way. Web browsers doesn't really like that. So, for handling large files, I would suggest to look at other alternative: (java, swf, javascript, ...)

Something I would like to give a try when I have some time is http://nodejs.org/
