Hello,
I'm new to PHP but I've spent a lot of time looking and trying.
My goal is to write a php script that would take a file and upload it
to an image host website through the use of multipart form post.

I've read on the php.net site and tried their examples, 1 of them with
fsockopen, that totally didn't work. Now I'm trying curl, and I'm
running into the problem where I get something like this:

* About to connect() to www.imageboo.com port 80 (#0)
* Trying 67.159.45.97... * connected
* Connected to www.imageboo.com (67.159.45.97) port 80 (#0)

The picture.jpg exists, but for some reason the "Content-Type:
multipart/form-data;
boundary=----------------------------8d605df41713" cuts off, I assume
picture data supposed to follow the boudary id?

Here is the code I'm using to try and post the image to this host:

<?php
//HTML form field for multipart/form-data is here
http://www.imageboo.com/index.php
$docurl = curl_init();
curl_setopt($docurl, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($docurl, CURLOPT_URL, "http://www.imageboo.com/upload.php");
curl_setopt($docurl, CURLOPT_VERBOSE, 1);
curl_setopt($docurl, CURLOPT_HEADER, 1);
curl_setopt($docurl, CURLOPT_POST, 1);
curl_setopt($docurl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($docurl, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($docurl, CURLOPT_POSTFIELDS, array("userfile"=>"{@picture.JPG}"));
$webpage = curl_exec($docurl);
echo "$webpage";
curl_close($docurl);
?>

Here is what I read on mailarchives here, PHP doesn't handle multipart
posts correctly, correct?, instead should use formadd with
CURLOPT_HTTPPOST and CURLFORM_FILE, HOWEVER these commands do not
exist in the PHP interface, so how can I upload images using multipart
form post? What am I doing wrong, has anyone come up with these
solutions or used such methods?

I've spent a couple of days trying to figure this out and so far :(
only switched over to using curl instead of fsockopen, and I don't
know how to use curl very well. It is important that the code be PHP,
because it needs to be run inside or as a script for integration.

Thank you very much.
