如何將數組轉換為 json object？

Question

我正在嘗試將值推送到數組中，它就像

[{"Monday":"11:30"},{"Monday":"12:00"},{"Monday":"23:00"},{"Tuesday":"11:30"},{"Tuesday":"12:00"},{"Tuesday":"23:00"}]

但我希望它像 object

{

"Monday" : [ "11:30", "12:00", "23:00"]

"Tuesday" : ["11:30","12:00","23:00"]

}

這是我的代碼片段

$timings = DoctorTimings::where('doctor_id', '=', $input['doctor_id'])->get();
$doctor_timings = [];

foreach($timings as $timing) {
    $day_id = $timing->day_id;
    $time_slot_id = $timing->time_slot_id;
    $day_id =  Days::where('id', '=', $day_id)->first()->day;
    $time_id = DB::table('time_slot')->where('id', '=', $time_slot_id)->select('time')->first()->time;  
    array_push($doctor_timings, array($day_id => $time_id));
}

$doctorTimings = json_encode($doctor_timings);

echo $doctorTimings;

Answer 1

您可以使用mapToGroups來獲取請求的格式。 但我不知道你的表結構，所以我得到了這些；

[{"Monday":"11:30"},{"Monday":"12:00"},{"Monday":"23:00"},{"Tuesday":"11:30"},{"Tuesday":"12:00"},{"Tuesday":"23:00"}]

放入集合中（假設您的 eloquent 集合返回這樣）

$timings = collect([
        ["Monday" => "11:30"],
        ["Monday" => "12:00"],
        ["Monday" => "23:00"],
        ["Tuesday" => "11:30"],
        ["Tuesday" => "12:00"],
        ["Tuesday" => "23:00"]
    ]);

    return $timings->mapToGroups(function ($item) {
        $day = array_key_first($item);

        return [$day => $item[$day]];
    });

打印這些；

{
  "Monday": [
    "11:30",
    "12:00",
    "23:00"
  ],
  "Tuesday": [
    "11:30",
    "12:00",
    "23:00"
  ]
}

編輯：（您在此處在線發布的相同數組 + 我用於解決方案的相同 function）

$days = ["Monday", "Monday"];
$time = ["11:30", "12:30"];
$doctor_timings = [];
for ($i = 0; $i < sizeof($days); $i++) {
    $day_id = $days[$i];
    $time_id = $time[$i];
    array_push($doctor_timings, [$day_id => $time_id]);
}

return collect($doctor_timings)->mapToGroups(function ($item) {
    $day = array_key_first($item);

    return [$day => $item[$day]];
});

哪個打印

{"Monday":["11:30","12:30"]}
