多维数组上的数组合并 [英] Array merge on multidimensional array

问题描述

要么我瞎了，要么在 SO 上的任何地方都找不到这个问题.昨天我在合并数组时遇到了问题，我可以在 SO 的帮助下解决这个问题.今天我再次遇到合并数组的问题，但这次是多维数组.

Either I'm blind or I can't find this problem anywhere here on SO. Yesterday I had a problem with merging arrays, which I could fix with the help of SO. Today I have, again, a problem with merging arrays, but this time it's with multidimensional Arrays.

我有一个数组 $usergroup['groups'] 和一个数组 $usergroup['lang']

I have an array $usergroup['groups'] and an array $usergroup['lang']

$usergroup['groups'] 看起来像这样:

Array
(
    [0] => Usergroup_Model Object
        (
            [id] => 1
            [deleted] => 0
        )

    [1] => Usergroup_Model Object
        (
            [id] => 2
            [deleted] => 0
        )

    [2] => Usergroup_Model Object
        (
            [id] => 3
            [deleted] => 0
        )

)

而 $usergroup['lang'] 看起来像这样:

Array
(
    [0] => Usergroup_Model Object
        (
            [id] => 
            [id_usergroup] => 1
            [name] => Administratoren
            [id_lang] => 1
        )

    [1] => Usergroup_Model Object
        (
            [id] => 
            [id_usergroup] => 2
            [name] => Benutzer
            [id_lang] => 1
        )

    [2] => Usergroup_Model Object
        (
            [id] => 
            [id_usergroup] => 3
            [name] => Gäste
            [id_lang] => 1
        )

)

我希望我的合并数组如下所示:

I want my merged array to look like this:

Array
(
    [0] => Usergroup_Model Object
        (
            [id] => 1
            [id_usergroup] => 1
            [name] => Administratoren
            [id_lang] => 1
            [deleted] => 0
        )

    [1] => Usergroup_Model Object
        (
            [id] => 2
            [id_usergroup] => 2
            [name] => Benutzer
            [id_lang] => 1
            [deleted] => 0
        )

    [2] => Usergroup_Model Object
        (
            [id] => 3
            [id_usergroup] => 3
            [name] => Gäste
            [id_lang] => 1
            [deleted] => 0
        )

)

我尝试了什么?

我尝试了 PHP 的几个合并函数(array_merge() 和 array_merge_recursive())，我得到的最接近的结果是，第二个数组(['lang']) 覆盖了第一个数组 (['groups']).为了解决这个问题，我尝试删除 lang 数组(始终是 id)上的空值.但这并不能解决问题.代码 - 目前 - 看起来像这样:

I've tried several merging functions (array_merge() and array_merge_recursive()) of PHP, the closest result I got was, that the second Array (['lang']) overwrote the first Array (['groups']). To fix that, I tried to remove the empty values on the lang Array (which is always id). But that does not fix it. The code - at the moment - looks like this:

public static function getAll()
{
  $usergroup['groups'] = self::find();
  $usergroup['lang'] = self::findInTable(array(
    'id_lang' => Language_Model::getDefaultLanguage()
  ), self::dbTranslationTable);
  foreach ($usergroup as $ug) {
    $ug = array_filter($ug, function($val) {
      return $val != '';
    });
  }
  return array_merge($ug);
}

返回命令中的 array_merge() 似乎根本没有做任何事情，所以我可能没有正确收集数据或者我把数组搞砸了(忘记添加 []，或者我没有)不知道……).我有点想念这里的树林.

The array_merge() on the return command doesn't seem to do anything at all, so I'm probably not gathering the data correctly or I mess something up with the Arrays (forgetting to add [], or I don't know...). I kinda miss the forest for the trees here.

有什么建议可以朝哪个方向发展?

Any suggestions in which direction I could go?

使用 Pé de Leão 提供的代码，我能够解决问题.我的函数现在看起来像这样:

With the code provided by Pé de Leão I was able to solve the problem. My function now looks like this:

public static function getAll()
{
  $usergroup['groups'] = self::find();
  $usergroup['lang'] = self::findInTable(array(
    'id_lang' => Language_Model::getDefaultLanguage()
  ), self::dbTranslationTable);
  $out = array();
  foreach ($usergroup['groups'] as $key => $value) {
    $out[] = (object) array_merge((array) $usergroup['lang'][$key], (array) $value);
  }
  return $out;
}

结果正是我想要的！

推荐答案

$out = array();
foreach ($arr1 as $key => $value){
    $out[] = (object)array_merge((array)$arr2[$key], (array)$value);
}
print_r($out)
