我有兩個具有以下結構的數組array 'main' => array 'firstYearStudents' => array 0 => '10' 1 => '12' 'secondYearStudents' => array 0 => '8' 1 => '9' 'total' => array 'totalFirstYear' => '22' 'totalSecondYear' => '17'但我想得到以下一個array 'main' => array 'firstYearStudents' => array 0 => '10' 1 => '12' 2 => '22' 'secondYearStudents' => array 0 => '8' 1 => '9' 2 => '17'但我不明白如何將“總”數組中的值附加到“主”數組中的值。你能告訴我應該朝哪個方向移動嗎？編輯：如果我有以下鍵以及上述鍵怎么辦？array 'main' => array 'firstYearStudents' => array 0 => '10' 1 => '12' 'secondYearStudents' => array 0 => '8' 1 => '9' 'programCode' => array 0 => '03.02.01' 1 => '03.01.01' 'total' => array 'totalFirstYear' => '22' 'totalSecondYear' => '17' 'programCode' => '-'那么所需的結構應該是這個樣子array 'main' => array 'firstYearStudents' => array 0 => '10' 1 => '12' 2 => '22' 'secondYearStudents' => array 0 => '8' 1 => '9' 2 => '17' 'programCode' => array 0 => '03.02.01' 1 => '03.01.01' 2 => '-'我嘗試了以下方法，但我得到了命名的密鑰，所以我無法訪問這些密鑰。$i = 0;foreach ($studentsEditInfo['main'] as $values) { $studentsEditInfo['main'] = array_merge($values, $studentsEditInfo['total'][$i]); $i++;}

您可以只映射主數組并推送其元素的總和：
$array['main'] = array_map(static function($counts) {
$sum = ctype_digit(implode('', $counts)) ? array_sum($counts) : '-';
return array_merge($counts, [$sum]);
}, $array['main']);
密鑰的值main將是您實際需要的：
array(2) {
["firstYearStudents"]=>
array(3) {
[0] => int(10)
[1] => int(12)
[2] => int(22)
}
["secondYearStudents"]=>
array(3) {
[0] => int(8)
[1] => int(9)
[2] => int(17)
}
["programCode"]=>
array(3) {
[0] => string(8) "03.02.01"
[1] => string(8) "03.01.01"
[2] => string(1) "-"
}
}

如果您只需要移動這兩個屬性，這應該是一個簡單的解決方案：
$data = [
'main' => [
'firstYearStudents' => [
'10',
'12'
],
'secondYearStudents' => [
'8',
'9'
]
],
'total' => [
'totalFirstYear' => '22',
'totalSecondYear' => '17'
]
];
$data['main']['firstYearStudents'][] = $data['total']['totalFirstYear'];
$data['main']['secondYearStudents'][] = $data['total']['totalSecondYear'];
如有必要，您應該能夠擴展它以涵蓋更多年，或者最終編寫一個循環來管理您需要的年數。
