Tenho este codigo abaixo que é um carrinho de compras, gostaria de saber como pego os valores deste session e colocar num banco de dados, ou simplismente mostra os dados desta session

<?php
session_start();
if(!isset($_SESSION['carrinho'])){
$_SESSION['carrinho'] = array();
$Lista = $_SESSION['carrinho'];
}

//adiciona produto

if(isset($_GET['acao'])){

//ADICIONAR CARRINHO
if($_GET['acao'] == 'add'){
$id = intval($_GET['id']);
if(!isset($_SESSION['carrinho'][$id])){
$_SESSION['carrinho'][$id] = 1;
}else{
$_SESSION['carrinho'][$id] += 1;
}
}

//REMOVER CARRINHO
if($_GET['acao'] == 'del'){
$id = intval($_GET['id']);
if(isset($_SESSION['carrinho'][$id])){
unset($_SESSION['carrinho'][$id]);
}
}

//ALTERAR QUANTIDADE
if($_GET['acao'] == 'up'){
if(is_array($_POST['prod'])){
foreach($_POST['prod'] as $id => $qtd){
$id = intval($id);
$qtd = intval($qtd);
if(!empty($qtd) || $qtd <> 0){
$_SESSION['carrinho'][$id] = $qtd;
}else{
unset($_SESSION['carrinho'][$id]);
}
}
}
}

}

?>

<?php echo $_SESSION['carrinho'][1]; ?>

Ou para ver tudo que tem gravado em sessão:

<?php print_r($_SESSION); ?>
