Remote PHP Posting

I'm building a PHP API for some software that allows file uploads. The software API given to us requires that file uploads along with form fields be posted to a remote address. I can do that with an HTML form, but I want to integrate this process into an existing server process to build a catalog of the user submitted files.

So in the end I need user submitted form fields stored locally and files stored through our remote software. What I really need is a PHP function that takes a set of form fields and a file pointer and posts them. Here's an example of something similar to what I need. This come from PHP: fsockopen online documentation.

<?php
# $host includes host and path and filename
    # ex: "myserver.com/this/is/path/to/file.php"
# $query is the POST query data
    # ex: "a=thisstring&number=46&string=thatstring
# $others is any extra headers you want to send
    # ex: "Accept-Encoding: compress, gzip\r\n"
function post($host,$query,$others=''){
    $path=explode('/',$host);
    $host=$path[0];
    unset($path[0]);
    $path='/'.(implode('/',$path));
    $post="POST $path HTTP/1.1\r\nHost: $host\r\nContent-type: application/x-www-form-urlencoded\r\n${others}User-Agent: Mozilla 4.0\r\nContent-length: ".strlen($query)."\r\nConnection: close\r\n\r\n$query";
    $h=fsockopen($host,80);
    fwrite($h,$post);
    for($a=0,$r='';!$a;){
        $b=fread($h,8192);
        $r.=$b;
        $a=(($b=='')?1:0);
    }
    fclose($h);
    return $r;
}
?>

Code (markup):

But this code doesn't handle multipart form data with a file upload, and I can't seem to make it work the way I need to with the file upload. Does anyone know how to do this?

Hi Stevecrozz that is simple and easy step to upload multiple files. Check this url and read the article I think this will help you out your problem.

I can already do that. I want to first do exactly that, then run my own code to alter it on my own server, then I want that server to re-POST to a second location on a remote server that I have no control over.
