#POSTing from PHP Curl
#----------------------
#First we initialised the connection, then we set some options using setopt(). 
#These tell PHP that we are making a post request, and that we are sending some 
#data with it, supplying the data. The CURLOPT_RETURNTRANSFER flag tells curl 
#to give us the output as the return value of curl_exec rather than outputting it. 
#Then we make the call and close the connection - the result is in $response.

$url = 'http://api.flickr.com/services/xmlrpc/';
$ch = curl_init($url);

curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $xml);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);

$response = curl_exec($ch);
curl_close($ch);


#POSTing from Pecl_Http
#----------------------
#This extension has a method to expressly post a request, and it can 
#optionally accept data to go with it, very simple and easy.
#Pecl_Http has two interfaces - one procedural and one object-oriented; 
#we'll start by looking at the former. This is even simpler than in curl, 
#here's the same script translated for pecl_http:

$url = 'http://api.flickr.com/services/xmlrpc/';
$response = http_post_data($url, $xml);

  

#POSTing from Pecl_Http: the OO interface
#----------------------  
#Finally let's see what the OO verison of the extension looks like. 
#Exactly the same call as both the above examples, but using the 
#alternative interface, means our code looks like this:

$url = 'http://api.flickr.com/services/xmlrpc/';

$request = new HTTPRequest($url, HTTP_METH_POST);
$request->setRawPostData($xml);
$request->send();
$response = $request->getResponseBody();
