我有一个5级嵌套数组，我想用自定义的方式对它进行排序。
经过一些排序后，结构为：
[shortcode1] => Array
(
[country1] => Array
(
[count] => 10
[revenue_value] => 11
)
)
[shortcode2] => Array
(
[country1] => Array
(
[count] => 24
[revenue_value] => 52
)
)
[shortcode3] => Array
(
[country2] => Array
(
[count] => 25
[revenue_value] => 52
)
)
我想要的结果是按国家对数组进行分组，并将其设置为：
[country1] => Array
(
[count] => 34 // sum of all counts of country1
[revenue_value] => 63 // sum of all revenue_values of country1
)
[country2] => Array
(
[count] => 25 // sum of all counts of country2
[revenue_value] => 52 // sum of all revenue_values of country2
)
这是我迄今为止的代码：
<?php foreach ($country_shortcode as $shortcode):
$count = 0;
$revenue = 0;
?>
<?php foreach ($shortcode as $country=>$value): ?>
<?php
$count += $value['count'];
$revenue += $value['revenue_value'];
$country_sum[$country] = array(
'count' => $count,
'revenue' => $revenue,
);
?>
<?php endforeach; ?>
<?php endforeach; ?>
但它只显示每个国家的最后一个值
更新+答案：
这是更新后的代码，正是我想做的。
$country_data;
<?php foreach ($country_shortcode as $shortcode):
$count = 0;
$revenue = 0;
?>
<?php foreach ($shortcode as $country=>$value): ?>
<?php
if (!isset($country_sum[$country])) $country_sum[$country] = array('count' => 0, 'revenue'=>0);
$country_sum[$country]['count'] += $value['count'];
$country_sum[$country]['revenue'] += $value['revenue_value'];
?>
<?php endforeach; ?>
<?php endforeach; ?>
这太容易了。。。只需在阵列上循环创建一个新的
foreach ($array as $sub) {
foreach ($sub as $countryName => $data) {
if (!isset($result[$countryName])) {
$result[$countryName] = ['count' => 0, 'revenue_value' => 0];
}
$result[$countryName]['count'] += $data['count'];
$result[$countryName]['revenue_value'] += $data['revenue_value'];
}
}
