如何将数组转换为json对象？

Question

我正在尝试将值推送到数组中，结果就像[{"Monday":"11:30"},{"Monday":"12:00"},{"Monday":"23:00"},{"Tuesday":"11:30"},{"Tuesday":"12:00"},{"Tuesday":"23:00"}]但我希望它成为一个对象{"Monday" : [ "11:30", "12:00", "23:00"]"Tuesday" : ["11:30","12:00","23:00"]}这是我的代码片段$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获取请求的格式。但是我不知道你的表结构所以我得到了这些；

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

放入集合中（假设你雄辩的集合像那样返回）

$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]];

    });

打印这些；

{

  "Monday": [

    "11:30",

    "12:00",

    "23:00"

  ],

  "Tuesday": [

    "11:30",

    "12:00",

    "23:00"

  ]

}

编辑：（你在网上发布的相同数组在这里使用+我用于解决方案的相同功能）

$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]];

});

哪个打印

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