我试图根据查询字符串值搜索ID。我已经设法找到相关的页面ID，但是，我需要得到父数组值以及…下面是一个正在运行的PHP数组的例子:

我试着在这里实现一些答案，因为我知道这是一个很好的话题，包括:
- 查找数组并返回匹配的键和值
- 如何在PHP多维数组中按键=>值进行搜索
但是两者的输出都是空白数组。
知道我需要做什么才能得到想要的输出吗?
EDIT:一些伪代码有望更清楚地解释这个问题
IF query string EQUALS id in array
load parent array (array that the id is in)
我希望这能让它更清楚一点!
找到了答案，我没有努力搜索，在这里找到了答案…
function search($array, $key, $value)
{
$results = array();
if (is_array($array)) {
if (isset($array[$key]) && $array[$key] == $value) {
$results[] = $array;
}
foreach ($array as $subarray) {
$results = array_merge($results, search($subarray, $key, $value));
}
}
return $results;
}
// $pageID being the query string
print_r(search($data, 'id', $pageID));
