Ok, i
$total_cost
which is equal to 529700
我需要价值5 297.00美元。
这一价值来自我的奇迹10,2 实地
现在,根据用户是否处于国家,我需要拿出2%的子和8.25%的航运。
让我们仅仅假设所有用户都是来自这个国家,那么,如何通过加拿大网站来保护这些用户。
例如,这是我的想法。
$subtotal = $total_cost * 0.02;
$shipping = $total_cost * 0.0825;
$new_total = $total_cost + $shipping + $subtotal;
但是,如果是印刷这种想法,则需要0美元。
<?php print "$". $new_total; ?>
在测试你的法典时,我没有获得这一结果。
php > $total_cost=529700;
php > $subtotal = $total_cost * 0.02;
php > $shipping = $total_cost * 0.0825;
php > $new_total = $total_cost + $shipping + $subtotal;
php > print "$". $new_total;
$583994.25
你们是否确信最初的价值是你们所期望的?
You need to see where this code breaks down, and that the values you think you have are actually there.... What does this output look like?
echo "Total: ".$total_cost."<br />";
$subtotal = $total_cost * 0.02;
echo "Sub: ".$subtotal . "<br />";
$shipping = $total_cost * 0.0825;
echo "Shipping: ".$shipping . "<br />";
$new_total = $total_cost + $shipping + $subtotal;
echo "New Total: ".$new_total . "<br />";
rel=“nofollow”>。 在产出期间,将数字分为100,由您计算和格式。
<?php print "$".number_format($new_total/100, 2); ?>
请注意,您可将数学合并为一份说明:
$new_total = $total_cost * 1.1025; // just add the numbers together and add 1
在计算百分比时,你必须将其改为浮动点数,或将 in合数降至0。
$subtotal = $totalcost / 100.0 * 0.02;
$shipping = $totalcost / 100.0 * 0.0825;
$newtotal = $totalcost / 100.0 + $subtotal + $shipping;
