【问题描述】：

所以，这是我用来获取数据的方法：

    $app->get('/people', 'getPeople');

    function getPeople(){
        $sql = "SELECT * FROM people";    
        try {
            $db = getConnection();
            $stmt = $db->query($sql);
            $entries = $stmt->fetchAll(PDO::FETCH_OBJ);
            $db = null;
            echo json_encode($entries);
        } catch(PDOException $e) {
            echo '{"error":{"text":'. $e->getMessage() .'}}';
        }

这是我的集合 (testsite.local/api/index.php/people) 的输出，看起来像这样：

    [
        {
            "month":"January",
            "week":"week1",
            "day":"monday",
            "photo":"pic.jpg",
            "name":"Mona Lisa"
        },
        {
            "month":"January",
            "week":"week2",
            "day":"monday",
            "photo":"pic.jpg",
            "name":"Michael Angelo"
        },
        {
            "month":"February",
            "week":"week1",
            "day":"tuesday",
            "photo":"pic.jpg",
            "name":"Da Vinci"
        }
    ]

所以我的问题是，我应该在哪里编辑什么内容才能使输出变成这样？？（这甚至可能吗？）

    [
        {
            "month":[
                {
                    "January":[
                        {
                            "week1":[
                                {
                                    "day":"monday",
                                    "photo":"pic.jpg",
                                    "name":"Mona Lisa"
                                }
                            ],
                            "week2":[
                                {
                                    "day":"monday",
                                    "photo":"pic.jpg",
                                    "name":"Michael Angelo"
                                }
                            ]
                        }
                    ],
                    "February":[
                        {
                            "week1":[
                                {
                                    "day":"tuesday",
                                    "photo":"pic.jpg",
                                    "name":"Da Vinci"
                                }
                            ]
                        }
                    ]
                }
            ]
        }
    ]

我对此很陌生，我真的无法弄清楚..提前谢谢:)

【解决方案1】：

我想这可能有用

    <?php
         $newArray = array();
         foreach($entries as $key => $entry){

         if($key === 'month'){
             $newArray[$key][$entry][$entries['week']] = array($entries->day,$entries->photo,$entries->name) 
         }
     }

     echo json_encode($newArray);

【解决方案2】：

在将 API 响应发送到视图之前，您始终可以使用 parse() 函数对其进行任何处理：

var PeopleCollection = Backbone.Collection.extend({
    url: '/people',
    parse: function(data) {
        // do some processing
        return data;
    }
})
