PhP - 搜索海量数组的值，返回父键。

Question

问：如何搜索单个值的大型多维数组，并返回父数组？<​​/ strong>

我有这个巨大的json代表了魔兽世界的所有成就。

http://us.battle.net/api/wow/data/character/achievements

我使用json_decode将其转换为数组。这给我留下了一个非常庞大的数组，我需要搜索它的所有级别，直到找到一个特定的值，然后我需要返回该值的父数组。

例如：

这是解码数组的一小部分。

            [accountWide] => 
            [factionId] => 2
        )

我正在尝试创建一个函数，我只需输入成就ID，在此示例中为7385，并且返回的父数组将为[0] => Array (...);，因此我可以从该阵列中获取成就细节。

我不确定这是否真的是一个正确的问题，因为我不确定从哪里开始。

到目前为止，我刚刚开始将原始的大规模阵列分解为10个同等大小的类别，然后逐个搜索它们，但我希望能够搜索主阵列一次而不是搜索每个类别数组单独

例如：

$allAchieves = file_get_contents('http://us.battle.net/api/wow/data/character/achievements');
$allAchieves = json_decode($allAchieves, true);

$generalAchieves = $allAchieves[achievements][0][achievements];
$quests = $allAchieves[achievements][1][categories];
$explorationAchieves = $allAchieves[achievements][2][categories];
$pvp = $allAchieves[achievements][3][categories];
$dungeonAndRaids = $allAchieves[achievements][4][categories];
$professions = $allAchieves[achievements][5][categories];
$reputation = $allAchieves[achievements][6][categories];
$scenarios = $allAchieves[achievements][7][categories];
$worldEvents = $allAchieves[achievements][8][categories];
$petbattle = $allAchieves[achievements][9][categories];
$featsOfStrength = $allAchieves[achievements][10][categories];

希望有人可以提供帮助，因为我在阵列搜索中看到的其他线程似乎太简单了，无法提供任何帮助，因为他们正在处理的数组与我在这里所拥有的数组相当。
