in php table tag not working

Question

I want the table tag to come before the display of records in cart() function but it is being displayed after it rather?

How to correct that and in cart() function in the display of records when I am trying <tr> and <td> tags to display its not working

  <?php
  session_start();

   $page = 'index.php';
   $connection = mysqli_connect("localhost","root","","cart");
if(isset($_GET['add']))
{
    if(array_key_exists('cart_'.$_GET['add'], $_SESSION))
        $_SESSION['cart_'.$_GET['add']]+= 1;
    else
        $_SESSION['cart_'.$_GET['add']] = 0;
    header("Location: cartindex.php");
}
if(isset($_GET['remove']))
{
    $_SESSION['cart_'.$_GET['remove']]--;
    header("Location: cartindex.php");
}
if(isset($_GET['delete']))
{
    $_SESSION['cart_'.$_GET['delete']]=0;;
    header("Location: cartindex.php");
}
function cart()
{
    global $connection;
    $total = 0;
    ?>
    <table class="table table-striped"><tr><th>ID</th><th>Name </th><th>Price Per Item</th><th>Cost</th><th>Add</th><th>Substract</th><th>Delete</th></tr>
    <?php foreach ($_SESSION as $key => $value) {

        if($value > 0)
        {
        $id = substr($key,5,strlen($key)-1);

        $result = mysqli_query($connection ,'select id,name,price from products where id ='.$id);
        while($row = mysqli_fetch_assoc($result))
            {
            $cost = $row['price'] * $value;
            echo $row['id'].'  '.$row['name'].'@'.$row['price'].'*'.$value.'='.$cost.'<a href="cart.php?add='.$id.'">[+]</a>'.'<a href="cart.php?remove='.$id.'">[-]</a>'.'<a href="cart.php?delete='.$id.'">[delete]</a>'.'<br>';
            $total = $total + $cost;
            }
        }
    }
    ?></table><?php
    if($total==0)
    {
        ///
    }
    else
    {
        $dis="'payment made'";
        echo 'Total cost is '.$total.'<br>';
        echo '<br><button type="button" class="btn btn-success" onclick="alert(\'Payment accepted\');">Success</button>';
    }
}
function product()
{
    $connection = mysqli_connect("localhost","root","","cart");
if(mysqli_connect_errno())
{
    die("not connected to db ".mysqli_connect_error());
}
    $get = mysqli_query($connection , "select id,name,description,price from products where quantity > 0 order by id DESC");

        while($row = mysqli_fetch_assoc($get))
        {
            echo '<div    class="boxed">'.$row['name'].'<br>'.$row['price'].'<br>'.$row['description'].'<br><a href="cart.php?add='.$row['id'].'" class="btn btn-primary btn-lg" role="button">ADD</a>'.'<br>'.'</div>';
        }
}

?>

Try replace "echo" with "return" inside functions.
