Using PHP curl to fetch post from del.icio.us

Been playing with del.icio.us's api to pull my del.icio.us ( very hard writing that ) post. php's curl made everything smooth. Below is the code. Feel free to comment on it.

$fetch_url ="https://api.del.icio.us/v1/posts/all?";
$curl = curl_init();
curl_setopt( $curl, CURLOPT_URL, $fetch_url );
curl_setopt( $curl, CURLOPT_RETURNTRANSFER, 1 );
curl_setopt( $curl, CURLOPT_USERPWD,"your username:your password");
curl_setopt( $curl, CURLOPT_CONNECTTIMEOUT, 30 );
curl_setopt( $curl, CURLOPT_TIMEOUT,5 );
curl_setopt( $curl, CURLOPT_POST, 1 );
$response = curl_exec( $curl );
curl_close( $curl );
header("Content-Type:text/xml");
echo $response;
