在PHP中创建一个包含数组数组的json对象

I'm using array_add($array, 'key', 'value'); to create the data structure.

foreach ($archives as $archive){
    $results = array_add($results, $archive->year, 
              array($archive->month => array('name' => $archive->month_name)));
}

If i json_encode()the $results i get this output:

{ 
   2015: {
       02: {name:'February'}
   }
}

But i want something like:

{
   2015: {
       02: {name:'February'},
       01: {name:'January'}
   }
}

And of course this should works for different years too.

    In response to my comments - here's what I'd do:

    foreach ($archives as $archive)
    {
        if (!isset($results[$archive->year]))
        {//if the year-key doesn't exist yet, create it
         //if it already exists, this part will be skipped
            $results[$archive->year] = array();
        }
        //then add the values
        $results[$archive->year][$archive->month] = array(
            'name' => $archive->month_name
        );
    }
    

    That's all there is to it, no need for a home-made function or anything like that
