用php上传文件到另一个php服务器

Question

I'm not asking about uploading a file from a browser to a php script, there's plenty of tutorials about that already. I'm asking about this:

I have a php script that has accepted a file from the user, and the file is currently on the hard disk of server 1. I want to upload the file from server 1 to a php script on server 2, using the regular Http post protocol, so the php script on server 2 can be written as a standard file-upload handler.

I cannot find any tutorial on the internet, because they all talk about browser->server1. The tutorials about php upload all talk about ftp, but I don't want to use that protocol.

Please help?

You can use CURL for this. Something like this should do it.

$ch = curl_init();
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, array('file' => '@/path/to/file.txt'));
curl_setopt($ch, CURLOPT_URL, 'http://server2/upload.php');
curl_exec($ch);
curl_close($ch);

You can then handle the the server2 part as a regular file upload. See curl_setopt() for more information on those options.
