Parse's REST API and PHP Curl requests - how to

I am using the excellent Parse as a data store, but need to access it through PHP (as a perhaps irrelevant bit of detail - I am having to access it through PHP in order for Facebook scrapers to recognise dynaically generated tags on my page).

Parse have a Rest API, and basic instructions on how to use them. For example, to retrieve an object:

curl -X GET \
-H "X-Parse-Application-Id: [My application ID]" \
-H "X-Parse-REST-API-Key: [My Parse Rest API key]" \
https://api.parse.com/1/classes/moods/

Unfortunately, I have no idea how to integrate this with PHP Curl examples I've seen online. I gather:

curl_setopt($ch, CURLOPT_USERPWD,

..might be involved. As might:

curl_setopt($ch, CURLOPT_URL, $Url);

but I could be way off. I am really sorry to not be able to figure this out myself - but I think this is still a valid question as it is very confusing to those who haven't used Curl/PHP before. Basically - I'm looking for information as basic as where to put the quoted example from the Parse docs...

Thanks in advance

EDIT:

Hey all, here is the solution as I configured it. Thanks to debianek for getting me going in the right direction.

if ($_GET['id']) {
$imageId = $_GET['id']; 
MyApplicationId = '[ID]';
$MyParseRestAPIKey = '[API Key]';
$url = 'https://api.parse.com/1/classes/images/'.$imageId;

$headers = array(
    "Content-Type: application/json",
    "X-Parse-Application-Id: " . $MyApplicationId,
    "X-Parse-REST-API-Key: " . $MyParseRestAPIKey
);

    $handle = curl_init(); 
curl_setopt($handle, CURLOPT_URL, $url);
curl_setopt($handle, CURLOPT_HTTPHEADER, $headers);
curl_setopt($handle, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($handle, CURLOPT_RETURNTRANSFER, true);
