我有一個 json 響應，如下所示：$response ='[ { "userSummaries": [ { "id": "9910", "status": "Active", "name": "Jhon" } ] }, { "userSummaries": [ { "id": "8754", "status": "Active", "name": "Jane" } ] }]';我想用userSummaries這個 php 代碼將其分組：$myArr = json_decode($response, true); $result_arr = []; array_walk($myArr,function($v,$k) use (&$result_arr){ $result_arr[key($v)] = $v[key($v)]; }); echo json_encode($result_arr);并且響應只返回一個數據：{"userSummaries":[{"id":"8754","status":"Active","name":"Jane"}]}是否可以得到這樣的輸出響應？：{"userSummaries":[{"id":"9910","status":"Active","name":"Jhon"}, {"id":"8754","status":"Active","name":"Jane"}, ]}通過網絡嘗試過，但沒有找到解決方案這是我的腳本： https: //3v4l.org/tVkK5也嘗試過這個：$class_array = array();foreach ($myArr as $sa) { $class_array[$sa['userSummaries']][] = array('name' => $sa['name']);}但返回：Notice: Undefined index: name in /in/hvSFC on line 28Warning: Illegal offset type in /in/hvSFC on line 28Notice: Undefined index: name in /in/hvSFC on line 28Warning: Illegal offset type in /in/hvSFC on line 28[]需要幫忙

你很接近。您只需要在每個循環中引用鍵和第一個userSummaries，而不是使用整個...
$myArr = json_decode($response, true);
$result_arr = ["userSummaries"=>[]];
foreach($myArr as $user) {
$result_arr["userSummaries"][] = $user['userSummaries'][0];
}
echo json_encode($result_arr);
結果是：
{"userSummaries":[
{"id":"9910","status":"Active","name":"Jhon"},
{"id":"8754","status":"Active","name":"Jane"}
]}
如果您預見每個中的 userSummaries 本身將有多個用戶......那么這將起作用：
$response ='[
{
"userSummaries": [
{
"id": "9910",
"status": "Active",
"name": "Jhon"
}
]
},
{
"userSummaries": [
{
"id": "8754",
"status": "Active",
"name": "Jane"
},
{
"id": "5421",
"status": "Active",
"name": "Bob"
}
]
}
]';
$myArr = json_decode($response, true);
$result_arr = ["userSummaries"=>[]];
foreach($myArr as $usergroup) {
foreach($usergroup['userSummaries'] as $user) {
$result_arr["userSummaries"][] = $user;
}
}
echo json_encode($result_arr);
結果是：
{"userSummaries":[
{"id":"9910","status":"Active","name":"Jhon"},
{"id":"8754","status":"Active","name":"Jane"},
{"id":"5421","status":"Active","name":"Bob"}
]}
