防止json_encode关联数组排序 [英] Prevent json_encode associative array sorting

问题描述

我有一个关联数组

Array(
   [289] => Array(
    'name'=> 'One'
   ),
   [292] => Array(
    'name'=> 'One'
   ),
   [290] => Array(
    'name'=> 'One'
   )
)

在此数组上使用json_encode之后.键是经过排序的，尽管我将其作为JSON对象获取.

After i use json_encode on this array. The keys are sorted, although i get it as JSON object.

有没有办法防止这种行为?

Is there way to prevent this behaviour?

推荐答案

没有标准规定必须按一定顺序进行.

there is no standard that says it has to be in a certain order.

请参见以下相关问题:

See this for a related question: How do you stop Chrome and Opera sorting JSON objects by Index ASC?

注意:我们正在谈论的是PHP函数，但结果基本上是javascript，因此有关不存在的标准的声明也适用.

btw:我已经使用以下代码对其进行了测试. PHP本身似乎没有对数组进行排序，firefox也没有(根据firebug控制台).

btw: I have tested it with the following code. PHP itself doesnt seem to sort the array, firefox doesn't as well (according to the firebug console).

<pre>
<?php
    $array = array();
    $array[289] = array('name'=>'One');
    $array[292] = array('name'=>'One');
    $array[290] = array('name'=>'One');
    print_r($array);
    $string = json_encode($array);
    print_r($string);
?>
</pre>
<script>
    var foo = <?=$string?>;
    console.log(foo);
</script>
