如果购物车商品= 0，则显示文字

Question

i'm having issues with the code i wrote up below. basically, when there are x items in the cart, it echoes the text "You have x item(s) in the cart". However, when there are no items, it should echo "You don't have any items in the cart" but instead echoes nothing. What am i doing wrong?

<?php 
    $array = unserialize($_SESSION['__vm']['vmcart']); 
    foreach($array->products as $product){
        $amount = $product->amount;
        if ($amount != 0){ echo "You have $amount item(s) in the cart."; } 
        else { echo "You don't have any items in the cart."; } 
    }
?>

Its because the code does not come in the for each loop.

<?php 
    $array = unserialize($_SESSION['__vm']['vmcart']); 
    if (count($array->products) > 0) {
      foreach($array->products as $product){
          $amount = $product->amount;
          echo "You have $amount item(s) in the cart."; 
          /* Do other thinks here. */
      }
    } else { 
     echo "You don't have any items in the cart."; 
    } 
?>

I'm not sure why you wanne use a loop btw.
