展开数据并构建新数组

Question

我需要分解一个数组的键值，并构建一个具有分解结果的新数组。下面的代码可用于一个子数组，我想我缺少一个for循环来照顾数组值的迭代。

该解决方案还应处理“财务”子数组数据，该数据将在新数组中分解并可见。

我在稍后阶段将有9个子数组，因此需要爆炸数据并将结果移到新数组中的原因。

我的代码

<?php

$array = [
  'company_info' => [
    'country_period_0'  => 10,
    'currency_period_0' => 20
  ],
  'finance'      => [
    'values_period_0' => 30
  ]
];

$newArray = [];

for ($i=0; $i <= 1 ; $i++) {

  $array_1     = $array['company_info'];
  $arrayKeys   = array_keys($array_1);
  $arrayValues = array_values($array_1);

  $keySplits   = explode("_", $arrayKeys[$i]);

  for ($i=0; $i <= 2 ; $i++) {
    $newArray[] = $keySplits[$i];
  }
    $newArray[3] = $arrayValues[0];

}

print_r($newArray);

结果

Array(
    [0] => country
    [1] => period
    [2] => 0
    [3] => 10
)

想要的结果

['company_info]
Array(
    [0] => country
    [1] => period
    [2] => 0
    [3] => 10
)
Array(
    [0] => currency
    [1] => period
    [2] => 0
    [3] => 20
)
['finance']
Array(
    [0] => values
    [1] => period
    [2] => 0
    [3] => 30
)

Answer 1

$new_array=[];
foreach($array as $category => $tmp ){

  foreach($tmp as $key => $value){
    $exp = explode('_', $key);
    $exp[] = $value;
    $new_array[ $category ][] = $exp;
    }

}
