$sql=mysql_query("select facebook_id,facebook_access_token from users where username='$user_session'");
$row=mysql_fetch_array($sql);
$facebook_id=$row['facebook_id'];
$facebook_access_token=$row['facebook_access_token'];
//Facebook Wall Update
params = array('access_token'=>$facebook_access_token, 'message'=>$status);
$url = "https://graph.facebook.com/$facebook_id/feed";
$ch = curl_init();

  3. Without using curl:
    include "facebook.php";
    if ($_POST['boton'] == "Public" ){
    $estado=$_POST['publicar'];
    $propiedades=array('message' => $estado);
    $facebook->api('/me/feed','post',$propiedades);
    }
    o api('/facebook_id/feed'

    Facebook Official PHP SDK you mentioned also uses cURL to interact with their API.

    @Tamada
    There is a small syntax glitch in the code you provided for update.php at around line 12.
