Facebook php connect

Im trying to connect to facebook using php-sdk. facebook login window appears when i click login, i fill my username and password and then it redirects to same page, saying not connected. I am new with facebook php. Help me

<?php
  require_once("php-sdk/src/facebook.php");

// Create our Application instance (replace this with your appId and secret).
$facebook = new Facebook(array(
  'appId'  => '---',
  'secret' => '---',
));

// Get User ID
$user = $facebook->getUser();

// We may or may not have this data based on whether the user is logged in.
//
// If we have a $user id here, it means we know the user is logged into
// Facebook, but we don't know if the access token is valid. An access
// token is invalid if the user logged out of Facebook.

if ($user) {
  try {
    // Proceed knowing you have a logged in user who's authenticated.
    $user_profile = $facebook->api('/me');
  } catch (FacebookApiException $e) {
    error_log($e);
    $user = null;
  }
}

// Login or logout url will be needed depending on current user state.
if ($user) {
  $logoutUrl = $facebook->getLogoutUrl();

}

You need to provide certain information to the app you just created. The call back url is needed. Please check the information at the facebook end.

Please place your appId and secret and follow the code below. You should also use the latest Facebook PHP SDK 

$facebook = new Facebook(array(
  'appId'  => '111111111',// your appId here
  'secret' => '1a1a1a1a1a1a1',// your app secret here
));


$user = $facebook->getUser();

if ($user) {
  try {
    $user_profile = $facebook->api('/me');

  } catch (FacebookApiException $e) {
    error_log($e);
    $user = null;
  }
}

if ($user) {
  $logoutUrl = $facebook->getLogoutUrl();



} else {
  $loginUrl = $facebook->getLoginUrl();
    echo "<script type='text/javascript'>top.location.href = '$loginUrl';</script>";
    exit;
}
