PHP HTTP header REST

I am developing an UI for a REST repository using PHP and the PEAR HTTP REQUEST package (http://pear.php.net/package/HTTP_Request/). I created a HTTP GET request and it delivers the requested rdf/xml file as expected. But I want to extend this request and I can't get this working. The repo开发者_JS百科sitory allows sending zip files which are attached to an id. So I have to call the same URL which delivers the rdf/xml data, but I have to change the HTTP GET header from xml to accept: application/zip, before executing my request. This should deliver the zip instead of the rdf/xml file.

$req =& new HTTP_Request();
$req->setMethod(HTTP_REQUEST_METHOD_GET);
$req->setURL($url);
$req->clearPostData();
if (!PEAR::isError($req->sendRequest())) {
     $response2 = $req->getResponseBody();
} else {
     $response2 = "";
}

echo $response2;

Does anyone know how to modify the GET call to get this done? I really need help!

Furthermore I want to create a HTTP PUT request which uses multipart/form-data. Does anyone know how to make this?

Please help me! Thanks!

For your first question, you can set the Accept field of your GET request header by:

$req->addHeader('Accept', 'application/zip');
# assuming that this will trigger the server to respond with the zip and not xml

Question number 2:

# Set method to PUT
$req->setMethod(HTTP_REQUEST_METHOD_PUT);

# Attach file to request
$req->addFile('file_upload_field', '/path/to/file.ext', 'application/zip');

Read up more on file uploads using HTTP_Request.

To modify the request headers, take a look at the addHeader() method of the HTTP_Request object: http://pear.php.net/manual/en/package.http.http-request.headers.php

To change the method, use the setMethod(): http://pear.php.net/package/HTTP_Request/docs/latest/HTTP_Request/HTTP_Request.html#methodsetMethod
