我正在尝试使用 php 将大文件上传到 ftp 服务器.我可以上传小文件，但上传大文件时遇到问题.我查了一下，发现需要设置upload_max_filesize和post_max_size，设置ftp为被动模式，设置时间限制为never.我没有设置时间限制，我现在没有返回任何错误，但它也没有上传文件.如果您查看底部的 if (!$upload) { 行，它应该会回显某些内容，但事实并非如此.更重要的是，它只是不起作用.关于出了什么问题或我需要做些什么来完成这项工作的任何见解?谢谢！
I'm trying to upload large files with php to an ftp server. I can upload small files, but I'm having trouble uploading larger files. I have looked it up and found that I need to set upload_max_filesize and post_max_size, set ftp to passive mode, and set time limit to never. I had no luck with setting the time limit, and what I have now isn't returning any errors, but it is also not uploading the file. If you look at the if (!$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 />";
}
}
我发现我无法从 php 页面设置 upload_max_filesize 值；另外，我似乎无法让 .htaccess 工作:如果我有一个 .htaccess 文件，则会导致 HTTP 错误 500.此外，我无权访问 php.ini.
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.
我还能如何更改upload_max_filesize 值?
How else can I change the upload_max_filesize value?
我的网络管理员告诉我，我使用的是基于 IIS Windows 的系统，因此 .htaccess 文件将无法工作.有没有办法可以通过 web.config 影响文件上传大小?
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?
来自这个网站:http://www.php.net/manual/en/ini.php
'upload_max_filesize' 和 'post_max_size'
'upload_max_filesize' and 'post_max_size'
属于 PHP_INI_PERDIR 类型
are of type PHP_INI_PERDIR
表示Entry可以在php.ini, .htaccess or httpd.conf"中设置.所以你不能在你的脚本中设置它.
which means Entry can be set in "php.ini, .htaccess or httpd.conf". So you can't set it in your script.

就个人而言，我想做同样的事情(通过 ftp 上传大文件)并最终编写一个 java 应用程序.对于处理大文件，php 并不是最好的方法.Web 浏览器并不喜欢这样.因此，对于处理大文件，我建议查看其他替代方案:(java, swf, javascript, ...)
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, ...)
