我现在正在处理数组，我需要根据值来安排它。

{
        "data": {
            "id": 2,
            "title": "second evaluation form",
            "emp_position": "System Architecture",
            "rating": 5,
            "segments": [
                {
                    "segment_name": "Job Role ",
                    "question": "How old are you?"
                },
                {
                    "segment_name": "360 Segments",
                    "question": "What is your food?"
                },
                {
                    "segment_name": "360 Segments",
                    "question": "sample question"
                },
            ]
        }
    }

我需要做的是将这个对象存储到数组中，并根据 segment_name 对所有问题进行分组，如下所示:

{
    "data":[
         {
            "id": 2,
            "title": "second evaluation form",
            "emp_position": "System Architecture",
            "rating": 5,
            "segments": [
                {
                    "segment_name": "Job Role "
                    "question_collection": [
                        {
                            "id": 4,
                            "question": "How old are you?"
                        }
                    ]


                },
                {
                    "segment_name": "360 Segments",
                    "question_collection":[
                        {
                           "id": 1,
                           "question": "What is your food?"
                        },
                        {
                             "id": 2,
                            "question": "sample question"
                         }
                    ] 
                },

            ]
        }
    ]
}

这就是我尝试做的:

 $array_value =[];       
        foreach ($query AS $key => &$data) {
            $array_value['id'] = $data['id'];
            $array_value['title'] = $data['title'];
            $array_value['emp_position'] = $data['position'];
            $array_value['rating'] = $data['rating_count'];                                  

            if ( is_array($data) ) {
               $array_value['segments'][$key]['segment_name'] = $data['segment'];                                  
               $array_value['segments'][$key]['question'] = $data['question'];                                  
            } 

        }

最佳答案

收集功能可能会帮助您找到解决方案。

$json = '{"data":{"id":2,"title":"second evaluation form","emp_position":"System Architecture","rating":5,"segments":[{"segment_name":"Job Role ","question":"How old are you?"},{"segment_name":"360 Segments","question":"What is your food?"},{"segment_name":"360 Segments","question":"sample question"}]}}';

    $array = json_decode($json, true);
    $coll = collect($array['data']['segments']);
    $coll = $coll->groupBy('segment_name');
    dump($coll);

希望这对你有帮助，如果有任何问题，请告诉我
