/* http://localhost/upload.php:
print_r($_POST);
print_r($_FILES);
*/
$ch = curl_init();
$data = array('name' => 'Foo', 'file' => '@/home/user/test.png');
curl_setopt($ch, CURLOPT_URL, 'http://localhost/upload.php');
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);

Notes
Note:
Passing an array to CURLOPT_POSTFIELDS will
encode the data as multipart/form-data,
while passing a URL-encoded string will encode the data as
application/x-www-form-urlencoded.
