基于键 PHP 的值总和
我们在 PHP 中有类似下面的数组，并且想要在新数组中创建一个新数组，应该有唯一的键，并且应该添加来自同一键的值。
Array
(
[0] => Array
(
[58] => 32.00
)
)
Array
(
[0] => Array
(
[58] => 34.00
)
)
Array
(
[0] => Array
(
[57] => 26.00
)
)
Array
(
[0] => Array
(
[57] => 27.00
)
)
Array
(
[0] => Array
(
[56] => 16.00
)
)
Array
(
[0] => Array
(
[56] => 17.00
)
)
我们想在上述数组的帮助下创建新数组。应添加相同键的值。新数组的输出应如下所示。
Array
(
[58] => 66
[57] => 53
[56] => 33
)
代码如下
minmaxarray 的输出是
Array
(
[0] => Array
(
[min] => 35.00
[max] => 50.00
[price] => 26.00
)
[1] => Array
(
[min] => 50.00
[max] => 80.00
[price] => 29.00
)
[2] => Array
(
[min] => 80.00
[max] => 100.00
[price] => 32.00
)
[3] => Array
(
[min] => 100.00
[max] => 150.00
[price] => 34.00
)
[4] => Array
(
[min] => 150.00
[max] => 180.99
[price] => 36.00
)
)
$shippingPrice = array();
foreach ($minmaxarray as $key => $value) {
if($price > $value['min'] && $price < $value['max'])
{
if($value['price'])
{
$shippingPrice[][$smethodid] = $value['price'];
break;
}
}
}
echo '<pre>'; print_r ($shippingPrice);
谢谢

如果您的数组结构始终与您发布的相同，那么此代码将为您工作：$example_array = array( array( '0' => 32.00 ), array( '2' => 32.00 ), array( '2' => 32.00 ));$new_array = array();// loop through every item in nested foreachforeach( $example_array as $value ) { foreach( $value as $key => $number ) { // if the array key not exist, calculate with 0, otherwise calculate with the actual value $new_array[$key] = isset($new_array[$key]) ? $new_array[$key] + $number : 0 + $number; }}print_r( $new_array );// prints Array ( [0] => 32 [2] => 64 )您的数组的代码示例：$shippingPrice = array();// loop through every item in nested foreachforeach( $minmaxarray as $value ) { foreach( $value as $key => $number ) { // if the array key not exist, calculate with 0, otherwise calculate with the actual value $shippingPrice[$key] = isset($shippingPrice[$key]) ? $shippingPrice[$key] + $number : 0 + $number; }}echo '<pre>';print_r( $shippingPrice ); -

你可以试试这段代码function array_flatten($array) { if (!is_array($array)) { return FALSE; } $result = array(); foreach($array as $key=> $value){ if (is_array($value)) { $result = array_merge($result, array_flatten($value)); } else { $result[$key] = $value; } } return $result; } 您通过数组调用此函数，然后函数将返回您预期的数组。array_flatten($array); -

您可以使用array_walk_recursive而不是 2foreach循环array_walk_recursive($arr, function($v,$k) use (&$r){ $r[$k] = isset($r[$k]) ? ($r[$k]+$v) : $v; });工作演示：- https://3v4l.org/MMDEv
