Question

我使用 for循环

创建了一个无数天的数组

"use strict";
var app = angular.module( "app",[],function( $routeProvider ) {
  $routeProvider.when( "/visitplace", {
    templateUrl: "placetovisit.html",
    controller: "TourCoordinatorCtrl",
    resolve: {
      "accommodation": function( $q, $timeout ) {
        var myFriend = $q.defer();
        $timeout(function(){
          myFriend.resolve({
            hotelName: function( ) {
              return "My Friend's friend's hotel";
            },
            roomNo: function( ) {
              return "404";
            }
          });
        },5000);
        return myFriend.promise;
      }
    }
  });
} );
app.controller( "TourCoordinatorCtrl", function( $scope, accommodation ) {
  $scope.name = "Shidhin";
  $scope.place = "Switzerland";
  $scope.hotel = accommodation.hotelName( );
  $scope.roomno = accommodation.roomNo( );
} );

并将此数组转换为json

$noOfDays=array();
for($i=1;$i<=31;$i++){
    if ($i == '1') {
        $noOfDays[$i]['Number']=$i;
        $noOfDays[$i]['Days']=$i.' Day';
    }else{
         $noOfDays[$i]['Number']=$i;
         $noOfDays[$i]['Days']=$i.' Days';
    }
}

$ noOfDaysjson返回json如下： -

echo $noOfDaysjson= json_encode($noOfDays);

但我不想要这个。显示为1,2，以json格式粗体显示

我怎样才能得到json： -

{**"1"**:{"Number":1,"Days":"1 Day"},**"2"**:{"Number":2,"Days":"2 Days"},**"3"**:{"Number":3,"Days":"3 Days"},**"4"**:{"Number":4,"Days":"4 Days"},"5":{"Number":5,"Days":"5 Days"},"6":{"Number":6,"Days":"6 Days"},"7":{"Number":7,"Days":"7 Days"},"8":{"Number":8,"Days":"8 Days"},"9":{"Number":9,"Days":"9 Days"},"10":{"Number":10,"Days":"10 Days"},"11":{"Number":11,"Days":"11 Days"},"12":{"Number":12,"Days":"12 Days"},"13":{"Number":13,"Days":"13 Days"},"14":{"Number":14,"Days":"14 Days"},"15":{"Number":15,"Days":"15 Days"},"16":{"Number":16,"Days":"16 Days"},"17":{"Number":17,"Days":"17 Days"},"18":{"Number":18,"Days":"18 Days"},"19":{"Number":19,"Days":"19 Days"},"20":{"Number":20,"Days":"20 Days"},"21":{"Number":21,"Days":"21 Days"},"22":{"Number":22,"Days":"22 Days"},"23":{"Number":23,"Days":"23 Days"},"24":{"Number":24,"Days":"24 Days"},"25":{"Number":25,"Days":"25 Days"},"26":{"Number":26,"Days":"26 Days"},"27":{"Number":27,"Days":"27 Days"},"28":{"Number":28,"Days":"28 Days"},"29":{"Number":29,"Days":"29 Days"},"30":{"Number":30,"Days":"30 Days"},"31":{"Number":31,"Days":"31 Days"}}

Answer 1

你需要的json表示你想要一个对象数组，如果那是你真正想要的，那么这将获得所需的结果。

<?php
$noOfDays=array();
for($i=1;$i<=31;$i++){
    $obj = new stdClass();
    $obj->Number = $i;
    if ($i == '1') {
        $obj->Days = $i. ' Day';
    }else{
        $obj->Days = $i. ' Days';
    }
    $noOfDays[] = $obj;

}
$noOfDaysjson = json_encode($noOfDays);
echo $noOfDaysjson;

Answer 2

这应该适合你：

<?php
$noOfDays=array();
for($i=1;$i<=31;$i++){
    if ($i == '1') {
        $noOfDays[] = [
            'Number' => $i,
            'Days' => $i. ' Days' 
        ];

    }else{
        $noOfDays[] = [
            'Number' => $i,
            'Days' => $i. ' Day' 
        ];
    }
}

echo $noOfDaysjson= json_encode($noOfDays);

Answer 3

最短且优化的方式：

$noOfDays = [];
for($i = 1; $i <= 31; $i++){
    $noOfDays[] = [
        'Number'=> $i,
        'Days' => $i . (($i == 1)? ' Day': ' Days' )
    ];
}

Answer 4

让你的数组多维，试试这个：

<?php
$noOfDays=array();
for($i=1;$i<=31;$i++){
    $noOfDays[] = [
                   'Number'=>$i,
                   'Days'=>$i. ($i == '1') ? ' Day' : ' Days'
                  ];
}

echo $noOfDaysjson= json_encode($noOfDays);

Answer 5

这里的所有答案都是正确的......

// in case you would like to change your array keys
define ('ARRAY_NUMBER', 'Number');
define ('ARRAY_DAYS',   'Days'  );

// i think it's more clean to avoid if else 31 times
$noOfDays = array();
$noOfDays[] = array(ARRAY_NUMBER    => 1,
                    ARRAY_DAYS      => '1 Day');

for ($i=2 ; $i<=31 ; $i++) {
    $noOfDays[] = array(ARRAY_NUMBER    => $i,
                        ARRAY_DAYS      => $i . ' Days');
}

var_dump(json_encode($noOfDays));
