PHP狀態檢查國家

Question

嗨必須檢查2個國家，以設置運輸成本。 （這些值先前通過下拉列表分配）。這是我的PHP條件，它似乎不工作。如果我犯了一個錯誤，有人可以幫助我解釋語法嗎？

<?php 
for($y = 0; $y < count($contentsArray); $y++) 
{ 

    $itemArray = explode(":", $contentsArray[ $y ]); 

    $price = number_format($itemArray[ 2 ] * $itemArray[ 1 ], 2); 
    $subtotal += $price; 

    echo "<tr>"; 
    echo "<td class='item_col'>" . $itemArray[ 0 ] . "</td>"; 
    echo "<td class='description_col'>" . $itemArray[ 3 ] . "</td>"; 
    echo "<td class='quantity_col'>" . $itemArray[ 1 ] . "</td>"; 
    echo "<td class='price_col'>$ " . $price . "</td>"; 
    echo "</tr>"; 
} 

// calculate the shipping 



if($subtotal > 500) 
    $shipping = 0.00; 

// ----這是我嘗試添加我的病情和錯誤------

else if ($country == "Canada") 
    $shipping = 10.00; 
else if ($country == "USA") 
    $shipping = 10.00; 

// ----在上面，我在那裏試圖添加我的條件------

else $ shipping = 15.00;

$shipping = number_format($shipping, 2); 




// calculate the tax and total for the cart 
$gst = number_format(($subtotal + $shipping) * 0.06, 2); 
$total = $subtotal + $shipping + $gst; 

// update the totals in the db 
$cartData->totals = $shipping . "|" . $gst . "|" . $total; 
$updateSuccess = updateCartTotals($merchant, $cartData); 
?> 

</tbody> 
</table>

<div id="invoice_totals"> 
    <div id="totals">

    <span class="total">$ <?=number_format($total, 2)?></span>

</div> 

</div>

爲了讓我們進一步幫助您，請在代碼中添加以下兩項補充（正是我在下面添加它們的位置）。運行它，然後將「DEBUG」消息粘貼到您的StackOverflow問題上。

<?php 
for($y = 0; $y < count($contentsArray); $y++) 
{ 

    $itemArray = explode(":", $contentsArray[ $y ]); 

    $price = number_format($itemArray[ 2 ] * $itemArray[ 1 ], 2); 
    $subtotal += $price; 

    echo "<tr>"; 
    echo "<td class='item_col'>" . $itemArray[ 0 ] . "</td>"; 
    echo "<td class='description_col'>" . $itemArray[ 3 ] . "</td>"; 
    echo "<td class='quantity_col'>" . $itemArray[ 1 ] . "</td>"; 
    echo "<td class='price_col'>$ " . $price . "</td>"; 
    echo "</tr>"; 
} 

// calculate the shipping 

// ADDITION #1 
echo "DEBUG: subtotal is $subtotal;<br>DEBUG: country is $country"; 
if($subtotal > 500) 
    $shipping = 0.00; 
// ---- This is where I'm trying to add my condition and bugs ------ 

else if ($country == "Canada") 
    $shipping = 10.00; 
else if ($country == "USA") 
    $shipping = 10.00; 
// ---- Above where I'm trying to add my condition ------ 

// ADDITION #2 
else $shipping = 15.00; 
echo "DEBUG: shipping is $shipping";
