我需要分解數(shù)組的鍵值并構(gòu)建一個(gè)具有分解結(jié)果的新數(shù)組。下面的代碼適用于一個(gè)子數(shù)組，我想我缺少一個(gè) for 循環(huán)來處理數(shù)組值迭代。該解決方案還應(yīng)處理“金融”子數(shù)組數(shù)據(jù)，以便在新數(shù)組中展開并顯示。我在后期會(huì)有 9 個(gè)子數(shù)組，因此需要分解數(shù)據(jù)并將結(jié)果移動(dòng)到新數(shù)組中。我的代碼<?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);結(jié)果Array( [0] => country [1] => period [2] => 0 [3] => 10)想要的結(jié)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)

您可以使用循環(huán)大大簡(jiǎn)化它foreach，尤其是每次獲取鍵和值以幫助構(gòu)建數(shù)組。
這也使用第一級(jí)的鍵explode()將結(jié)果添加到using ，但也只是將值添加到數(shù)組的末尾 using ... $newArray$newArray[$mainKey][][]
foreach ( $array as $mainKey => $elements ) {
foreach ( $elements as $subKey => $value ){
$newData = explode("_", $subKey);
$newData[] = $value;
$newArray[$mainKey][] = $newData;
}
}
用你的測(cè)試數(shù)據(jù)給出......
Array
(
[company_info] => Array
(
[0] => Array
(
[0] => country
[1] => period
[2] => 0
[3] => 10
)
[1] => Array
(
[0] => currency
[1] => period
[2] => 0
[3] => 20
)
)
[finance] => Array
(
[0] => Array
(
[0] => values
[1] => period
[2] => 0
[3] => 30
)
)
)
我只是注意到我丟失了第二個(gè)company_info數(shù)據(jù)，所以這意味著值將始終是數(shù)組，除非你真的只在需要時(shí)才需要它們是數(shù)組。

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