您好,我有一个基本的 php 脚本,用于显示数组中一组项目的价格。该数组包含 3 条信息:名称、价格和 sku。价格可以设置为 99.95、12.95、10.50 或仅 5.00。到目前为止,一切似乎都运行良好,但是当我尝试报告任何价格,如 5.00 或 10.00(整数金额)时,它只会截断结尾的 .00,这并不是一个问题,但我宁愿让它显示尾随零,所以一切看起来不错,很相似。这是数组/报告循环的代码:
$items = Array
(
"0"=> Array
(
"name" => $_SESSION['itemname-mo'],
"price" => $_SESSION ['price-mo'],
"sku" => $_SESSION ['sku-mo']
),
"1" => Array
(
"name" => $_SESSION['itemname-addon'],
"price" => $_SESSION ['price-addon'],
"sku" => $_SESSION ['sku-addon']
),
"2" => Array
(
"name" => $_SESSION['itemname-addon1'],
"price" => $_SESSION ['price-addon1'],
"sku" => $_SESSION ['sku-addon1']
),
"3" => Array
(
"name" => $_SESSION['itemname-addon2'],
"price" => $_SESSION ['price-addon2'],
"sku" => $_SESSION ['sku-addon2']
)
);
$a_length = count($items);
for($x = 0; $x<$a_length; $x++){
$total +=$items[$x]['price'];
}
echo "<div class=\"well\">";
for($i = 0; $i < $a_length; $i++){
$name = $items[$i]['name'];
$price = $items[$i]['price'];
$sku = $items[$i]['sku'];
displaycart($name,$price,$sku);
}
echo "<br />
Sub Total:
$$total";
echo "</div>";
function displaycart($name,$price,$sku){
if($name != null || $price != null || $sku != null){
echo "$name: $$price ($sku) <br />";
}
else{ echo "";}
}
