考慮一下 PHP 中的這個對象數組： array:2 [ 0 => array:4 [ "Row_Id" => 256 "Start_Date" => "2020-05-16" "account_code" => "" "caller_number" => "452" ] 1 => array:4 [ "Row_Id" => 257 "Start_Date" => "2020-05-16" "account_code" => "" "caller_number" => "42" ] 2 => array:4 [ "Row_Id" => 258 "Start_Date" => "2020-05-16" "account_code" => "" "caller_number" => "428" ] ]我想添加"callee_number:100"每個數組，所以我的輸出應該如下所示： array:2 [ 0 => array:5 [ "Row_Id" => 256 "Start_Date" => "2020-05-16" "account_code" => "" "caller_number" => "452" "callee_number" => "100" ] 1 => array:5 [ "Row_Id" => 257 "Start_Date" => "2020-05-16" "account_code" => "" "caller_number" => "42" "callee_number" => "100" ] 2 => array:5 [ "Row_Id" => 258 "Start_Date" => "2020-05-16" "account_code" => "" "caller_number" => "428" "callee_number" => "100" ] ]我已將上述輸入數組放入 $get 變量中?，F在我調用array_push附加callee_number到每個數組： array_push($get,[ 'callee_number':'100' ]);也嘗試使用array_merge但callee_number沒有被附加。我怎樣才能做到這一點？

給定以下數組：
$array = [
[
"Row_Id" => 256,
"Start_Date" => "2020-05-16",
"account_code" => "",
"caller_number" => "452",
],
[
"Row_Id" => 257,
"Start_Date" => "2020-05-16",
"account_code" => "",
"caller_number" => "42",
],
[
"Row_Id" => 258,
"Start_Date" => "2020-05-16",
"account_code" => "",
"caller_number" => "428",
],
];
原生 PHP
$array = array_map(function ($item) { return $item + ['callee_number' => 100]; }, $array);
使用集合
$array = collect($array)->map(function ($item) { return $item + ['callee_number' => 100]; })->toArray();
使用 PHP 7.4 簡寫
$array = array_map(fn($item) => $item + ['callee_number' => 100], $array);
// Or
$array = collect($array)->map(fn($item) => $item + ['callee_number' => 100])->toArray();

要添加或修改每個子數組中的元素，您可以這樣做：
foreach ($get as &$g) {
$g["callee_number"] = 100;
}
或這個：
for ($c = 0; $c < count($get); $c++) {
$get[$c]["callee_number"] = 100;
}
