请原谅我标题中的双关语(呵呵),但这真的让我抓狂!这是我的代码:
for ($i=0;$i < $a;$i++){
$total = (array)$orders -> Total -> Line[$i];
echo '<pre>';
print_r($total);
echo '</pre>';
}
它输出以下内容:
Array
(
[@attributes] => Array
(
[type] => Subtotal
[name] => Subtotal
)
[0] => 299.99
)
Array
(
[@attributes] => Array
(
[type] => Shipping
[name] => Shipping
)
[0] => 13.36
)
Array
(
[@attributes] => Array
(
[type] => Tax
[name] => Tax
)
[0] => 0.00
)
Array
(
[@attributes] => Array
(
[type] => GiftCertificate
[name] => Gift certificate discount (117943:@CAC7HXPXFUNNJ3MTGC:63.35 117372:@DK9T9TMTCTCTUWF9GC:250.00)
)
[0] => -313.35
)
Array
(
[@attributes] => Array
(
[type] => Total
[name] => Total
)
[0] => 0.00
)
我的问题是:如何将每个美元金额[0]保存到根据数组['type']命名的相应变量中?
我建议将它们放入由type
属性键控的数组$prices
中,而不是一个变量(可以用变量变量来完成)。
$prices = array();
for ($i=0;$i < $a;$i++){
$total = (array)$orders -> Total -> Line[$i];
echo '<pre>';
print_r($total);
echo '</pre>';
// Append the price to an array using its type attribute as the
// new array key
$prices[$total['@attributes']['type']] = $total[0];
}
当然,没有经过测试,但我相信它会完成任务。
$var[] = array('type' => $total['@attributes']['type'], 'amount' => $total[0])
可能是这样的吗?
$total_amount_by_type = array();
for ($i=0;$i < $a;$i++){
$total = (array)$orders -> Total -> Line[$i];
$total_amount_by_type[$total->type] = $total[0]
}
你在寻找这样的东西吗:
for ($i=0;$i < $a;$i++){
$total = (array)$orders -> Total -> Line[$i];
// will create variables $Tax, $GiftCertificate etc
${$total['@attributes']['type']} = $total[0];
echo '<pre>';
print_r($total);
echo '</pre>';
}
