PHP upload field destination of other server

I have a website which I'll call website.com that is located on server1. website.com has a field to upload a file. When someone uploads 开发者_Python百科a file on website.com, I don't want the file uploaded to server1, I want it to upload to another server, server2. What is the best way to do this? Can I do this using php, a shell script?

After the file is uploaded to server2, I have a shell script to execute on the file which I will also eventually have to figure out how to run from server1.

I hope this makes sense, thanks in advance.

another possible way to do this is by uploading this file to your website.com site and use CURL to send the image to another server. once this completes you can remove the image again.

see CURL PHP send image for more information.

-- UPDATE --

For SSH connection you need to install additional libraries in order to allow php to make SSH connection. an excellent tutorial can be found here.

-- UPDATE 2 -- The question intrigued me, so i expanded my research. there seems to be another PHP Library phpseclib around on Sourceforge. In the documentation on page 5 there is some information on how it works.

The only good way to make this to work is to read the image to binary, and send it over the the other server, as text and write that into an file, hence creating an image from the source of the original. Also place the image in a public folder that is accepts calls from your website1 domain, this way you also prevent hot linking your images and saves considerable data.

I also came across this for help with phpseclib.

in the end i wouldnt choose for a solution like this. I would swap your website from server1 to server2, just to keep everything in one place.

Cant you put the script to handle the upload on Server 2?

You can have your HTML pages with the form served for server 1, but call the PHP for the upload from server 2.

Update For example...

Server 1 has a file index.php which has a form:

<form action='http://server2.com/some_directory/uploader.php' method='POST'>
 .... Some form code
</form>

The form on index.php points to a PHP script on server 2, via a URL. That PHP script can now handle the input.

Of course this will only work if server2 is connected accessible from the internet, if not you will have to use some sort of shell script on server 1 to move the files on the internal network when they are uploaded to server 1.
