Google docs POST request - google-docs-api

Question

I'm developing a web aplication which interacts with google docs through api.
As Zend_Gdata doesn't have methods to change the sharing permitions of documents I need to use the POST method as the following:
POST /feeds/default/private/full/resource_id/acl HTTP/1.1
Host: docs.google.com
GData-Version: 3.0
Authorization: <your authorization header here>
<entry xmlns="http://www.w3.org/2005/Atom" xmlns:gAcl='http://schemas.google.com/acl/2007'>
<category scheme='http://schemas.google.com/g/2005#kind'
term='http://schemas.google.com/acl/2007#accessRule'/>
<gAcl:role value='writer'/>
<gAcl:scope type='user' value='new_writer#example.com'/>
</entry>
Where exactly do I do this? Does php has a POST function? Should I use curl to do it? and how?
Thanks in advance

Answer 1

PHP can everything.
$url = "http://docs.google.com/feeds/default/private/full/resource_id/acl";
$headers = array("GData-Version: 3.0",
"Authorization: <your authorization header here>");
$body = "<entry xmlns="http://www.w3.org/2005/Atom"
xmlns:gAcl='http://schemas.google.com/acl/2007'>
<category scheme='http://schemas.google.com/g/2005#kind'
term='http://schemas.google.com/acl/2007#accessRule'/>
<gAcl:role value='writer'/>
<gAcl:scope type='user' value='new_writer#example.com'/>
</entry>";
// main options
curl_setopt($this->curl, CURLOPT_URL, $url);
curl_setopt($this->curl, CURLOPT_POST, true);
curl_setopt($this->curl, CURLOPT_HTTPHEADER, $headers);
if (!empty($body)) curl_setopt($this->curl, CURLOPT_POSTFIELDS, $body);
$response = curl_exec($this->curl);
