我在下面写的代码有问题。基本上,当购物车中有x个商品时,它会回显文本"You have x item(s) in the cart“。然而,当没有商品时,它应该回显“你购物车中没有任何商品”,而不是什么都不回显。我做错了什么?
<?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."; }
}

这是因为代码没有出现在for each循环中。
<?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.";
}
?>我不知道你为什么要使用循环btw。
