How to pass customer information from magento to codeigniter in same domain

Question

How can I pass the customer session and information from Magento to Codeigniter in same domain. In codeigniter I have created a function to check the customer session then if the customer is logged in then returning the customer information or else redirecting to magento customer login page if not.

In codeigniter Created a function as

public function loggedIn(){

    //$customerInfo = array();
    $dir = $_SERVER['DOCUMENT_ROOT'];
    $fullPath = $dir.'/magento/app/Mage.php';
    echo $fullPath;

    require_once( "$fullPath" );
    umask(0);

    // Initialize Magento
    Mage::app();

    // You have two options here,
    // “frontend” for frontend session or “adminhtml” for admin session
    Mage::getSingleton('core/session', array('name' => 'frontend'));
    $session = Mage::getSingleton('customer/session', array('name'=>'frontend'));
    $customer_data = Mage::getModel('customer/customer')->getCustomer();
    if($session->isLoggedIn()){
    echo "Logged In";
    var_dump($customer_data);
    }
    else{
    echo "Logged out";
    header('Location:http://localhost/magento/customer/account');
   // Mage::app()->getFrontController()->getResponse()->setRedirect(""); 

    }

 }  

When customer is loggedIn in magento then it shows "Logged In" and for logged out user it is redirecting. However, it is not showing any logged in user information.

I had tried both-- getSingleton('customer/session') and getModel('customer/customer'); but it is not returning any value. And How can I use entire magento functionality in there. I am not able to use redirect function as well so just used PHP header function.

Thanks in advance

You are using a not getting the customer from the session. You are creating an instance of the customer model and calling a method that returns null. getCustomer is the same as getData('customer') on the customer model. This is always null.
Try it like this:

$session = Mage::getSingleton('customer/session');
if ($session->isLoggedIn()) { //if the customer is logged in
    return $session->getCustomer();
}
else {
    //the customer is not logged in
    return false;//or do what ever you want for this case
}
