$prices 具有以下值
Array
(
[0] => 824.2776
[1] => 1586.5128
[2] => 2277.8424
[3] => 2902.698
[4] => 3465.5112
[5] => 3957.4188
)
我也有一些代金券代码，$vArray如下所示：
Array
(
[voucher1] => 30
[voucher2] => 40
)
我想创建一个减去一定百分比的价格。在这种情况下，分别是30％和40％...只是不确定如何。
foreach($prices as $price){
foreach($vArray as $key => $value){
$prices[] = ($value / $price) * 100;
}
}
上面的foreach在中创建这些其他数组项 $prices
[6] => 3.6395505591805
[7] => 1.8909396759988
[8] => 1.3170358054622
[9] => 1.0335212274925
[10] => 0.86567315090484
[11] => 0.75806988130748
$prices = [
100,
824.2776,
1586.5128,
2277.8424,
2902.698,
3465.5112,
3957.4188
];
$vArray = [
'voucher1' => 30,
'voucher2' => 40,
];
foreach ($prices as $price) {
foreach ($vArray as $voucherId => $percentage){
$prices[] = $price * (1 - ($percentage / 100));
}
}
print_r($prices);
输出：
Array
(
[0] => 100
[1] => 824.2776
[2] => 1586.5128
[3] => 2277.8424
[4] => 2902.698
[5] => 3465.5112
[6] => 3957.4188
[7] => 70
[8] => 60
[9] => 576.99432
[10] => 494.56656
...
[20] => 2374.45128
)
