如何在FTP服务器上使用PHP上传大文件？

问题描述：

$ftp_server = 'ftp.abc.com';
$remote_file = "myvideo.avi";  // file size 210MB
$file = "myvideo.avi";        // file size 210MB
$conn_id = ftp_connect($ftp_server);  // set up basic connection

// login with username and password
$login_result = ftp_login($conn_id, 'faraz@abc.com', 'password');

ftp_pasv($conn_id, true); // turn passive mode on
// upload a file
if (ftp_put($conn_id, $remote_file, $file, FTP_ASCII)) {
     echo "successfully uploaded $file\n";
} else {
     echo "There was a problem while uploading $file\n";
}
    // close the connection
    ftp_close($conn_id);

i already edit php.in for
upload_max_filesize = 1024M

上面的代码片段处理所有类型的文件上传，

，但是当我试图上传一个大尺寸的文件，然后上传到服务器上，但上传后大小变化。

本地机器上的视频文件大小-210MB

，但是上传后，它在FTP服务器上显示的文件大小为328KB。

i不知道我在哪里检查，如果有人有建议，那么我赞赏

above snippet working on all types of file(s) upload,
but when am trying to upload a large size file then it upload on server but size varies after uploading.
A video file size-210MB on local-machine
but after upload, it displayed file size 328KB on FTP-server.
i have no idea where do i check, if someone has suggestion then i appreciates

答

使用 FTP_BINARY 而不是 FTP_ASCII 。后者可能会停在第一个NUL字节。

Use FTP_BINARY instead of FTP_ASCII. The latter might stop at the first NUL byte.

除此之外，现在没有理由使用ascii模式，即使是ascii文件。只有在的情况下，如果您的cgi脚本包含一个在本地具有windows linebreaks的shebang行，这一点很重要。

Besides that, there is no good reason to use ascii mode nowadays, even for ascii files. The only case where it's important if you have cgi scripts containing a shebang line that have windows linebreaks locally.
