By default, all HTTP requests made out by cURL is GET requests that simply fetches the URL and don’t submit any more POST variables.

However, if you need to fetch and retrieve URL by the POST method with cURL, you need the snippet below:

$url = 'http://www.example.com/submit.php';
// The submitted form data, encoded as query-string-style
// name-value pairs
$body = 'monkey=uncle&rhino=aunt';
$c = curl_init ($url);
curl_setopt ($c, CURLOPT_POST, true);
curl_setopt ($c, CURLOPT_POSTFIELDS, $body);
curl_setopt ($c, CURLOPT_RETURNTRANSFER, true);
$page = curl_exec ($c);
curl_close ($c);

Make sure you have set CURLOPT_POST to true and attached the POST variables in the form of a GET series of name=value couples by CURLOPT_POSTFIELDS.
