How can I programatically get the cart's dollar sum of drupal commerce?

Question

For future users <?php echo '$' . number_format(( $total['amount'] /100),2); ?> is how.

---

Following this guide http://kahthong.com/2012/08/programmatically-show-number-items-drupal-commerce-shopping-cart I got the cart item total using

<?php
global $user;
$quantity = 0;
$order = commerce_cart_order_load($user->uid);
if ($order) {
    $wrapper = entity_metadata_wrapper('commerce_order', $order);
    $line_items = $wrapper->commerce_line_items;
    $quantity = commerce_line_items_quantity($line_items, commerce_product_line_item_types());
    $total = commerce_line_items_total($line_items);
    $currency = commerce_currency_load($total['currency_code']);
}
print format_plural($quantity, '1 item', '@count items');
?>

however when I try to get the dollar total using <?php print $total; ?>, it just returns 'Array'.

I used Devel on the page, but the cart is just a bunch of markup in ['content']['system_main']['main']['#markup']. What I want is <span class="line-item-total-raw">$106.00</span>, is there a way I can grab that class specifically with php somehow? Or maybe there's another way to go about this.

You should have it already. That call to "commerce_line_items_total" returns the array:

return array('amount' => $total, 'currency_code' => $currency_code);

Thus you should have the total price at $total['amount'] since you already have $total['currency_code']
