文件上传并保存到另一台服务器PHP

Question

I currently collect and upload an image using a form on one server (server A), I would like to store it on another server (server B). From the examples I have seen, I would need to save the file and then copy it over using either copy or curl.

I would like to get the file that I receive on server A and send it to server B without actually saving the file on server A. Is there a way for me to do this? I tried converting the file to a dataURI string and sending it this way, however I think the string is too long and I am getting errors with this. Thank you in advance for your help!

UPDATE I found my solution lovers! The file is stored in temporary storage when uploaded. You can't use just the filename to save the file on a different server, but you can use the information to create a CurlFile, which can then be passed to your page on the other server to be created (See Shivani Patel's response to PHP: upload file from one server to another server ). This combined with information from http://blog.derakkilgo.com/2009/06/07/send-a-file-via-post-with-curl-and-php/ and I got my code working.

Please mark as duplicate if appropriate. I didn't think to look into the temp filename until suggested :)

You can make use of ftp_put() function as follows

// information of second server
$ftp_server = "ftp.example.com";
// name file in serverA that you want to store file in serverB
$file = 'somefile.png';
$remote_file = 'serverB_file.png';

// set up basic connection
$conn_id = ftp_connect($ftp_server);

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

// 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";
}

I have also gone same thing.. first i moveuploaded file in serverA and then transfer in serverB,,, after complete transfer unlink the file in serverA.
