我该怎么办`json_en code（）`从PHP数组键？ [英] How do I `json_encode()` keys from PHP array?

问题描述

我有打印一个这样的数组

 阵列（[0] =＆GT; 1691864 [1] =＆GT; 7944458 [2] =＆GT; 9274078 [3] =＆GT; 1062072 [4] =＆GT; 8625335 [ 5] =＆GT; 8255371 [6] =＆GT; 5476104 [7] =＆GT; 6145446 [8] =＆GT; 7525604 [9] =＆GT; 5947143）
 

如果我 json_en code（$ thearray）我得到这样

  [1691864,7944458,9274078,1062072,8625335,8255371,5476104,6145446,7525604,5947143]
 

为什么名称不带codeD（例如0，1，2，3等）？我应该怎么做，使之出现在JSON code？
全code是低于

  $即= 0;
  而（$即10）
  {
    $ genid，配置=兰特（1000000,9999999）;
     $临时[$即] = $ genid，配置;
     $即++;
     }
     的print_r（$ TEMP）;    $ temp_json = json_en code（$ TEMP）;
    的print_r（$ temp_json）;
 

解决方案

您可以强制 json_en code 使用，虽然你是通过设置传递用数字键数组的对象的 JSON_FORCE_OBJECT 的选项：

  json_en code（$ thearray，JSON_FORCE_OBJECT）
 

则返回值将与数字键的JSON对象：

<$p$p><$c$c>{\"0\":1691864,\"1\":7944458,\"2\":9274078,\"3\":1062072,\"4\":8625335,\"5\":8255371,\"6\":5476104,\"7\":6145446,\"8\":7525604,\"9\":5947143}

但你只能这样做，如果确实需要的对象。

I have an array which prints like this

Array ( [0] => 1691864 [1] => 7944458 [2] => 9274078 [3] => 1062072 [4] => 8625335 [5] => 8255371 [6] => 5476104 [7] => 6145446 [8] => 7525604 [9] => 5947143 )

If I json_encode($thearray) I get something like this

[1691864,7944458,9274078,1062072,8625335,8255371,5476104,6145446,7525604,5947143]

Why the name is not encoded (e.g 0, 1 , 2 , 3 etc) ? and how should I do to make it appear in the json code? the full code is below

  $ie = 0;
  while($ie   10)
  {
    $genid = rand(1000000,9999999);
     $temp[$ie] = $genid ;
     $ie++;
     }
     print_r($temp);

    $temp_json = json_encode($temp);
    print_r($temp_json);

解决方案

You can force that json_encode uses an object although you’re passing an array with numeric keys by setting the JSON_FORCE_OBJECT option:

json_encode($thearray, JSON_FORCE_OBJECT)

Then the returned value will be a JSON object with numeric keys:

{"0":1691864,"1":7944458,"2":9274078,"3":1062072,"4":8625335,"5":8255371,"6":5476104,"7":6145446,"8":7525604,"9":5947143}

But you should only do this if an object is really required.
