在嵌套关联数组中查找值

Question

我希望使用'SamAccountName'的值获取'GUID'的值。即我只有值's'SamAccountName'，我想获得该数组部分的'GUID'值。

这最初是一个stdClass对象，但我使用json_decode（json_encode（$ obj），true）转换为关联数组。

Answer 1

您可以使用简单的循环来获取它

$id = 0;
foreach($data as $item) {
  if (isset($item['SamAccountName']) && 'accountName' == $item['SamAccountName']) {
    $id = $item['GUID'];
    break;
  }
}
var_dump($id);

Answer 2

这就是你要找的东西吗？

function findBySam($arrayList, $sam) {

    foreach($arrayList as $array) {
      if($array['SamAccountName'] == $sam) {
        return $array;
      }
    }
    return false;
}

Answer 3

听起来你想获得'SamAccountName'值的GUID部分。使用foreach循环：

function getGUID($san, $array) {
    foreach($array as $a) {
        if($a['SamAccountName'] == $san) {
            return $a['GUID'];
        }
    }
    return false;
}

$guid = getGUID("SamAccountNameHere", $yourArray);

Answer 4

以下是您可以使用的功能示例。这假定在数组中只有一个具有SamAccountName的对象（它只使用它找到的第一个对象）。它返回匹配数组的GUID，如果找不到匹配SamAccountName的数组，则返回false。

function getGuidForSamAccountName($arr, $name) { 
    foreach ($arr as $elem) {
        if ($elem['SamAccountName'] === $name) {
            return $elem['GUID'];
        }
    }
    return false; //No match found
}

Answer 5

你可以使用php的array_filter函数： http://php.net/manual/en/function.array-filter.php

示例：

$GUID = "sample";
array_filter($array, "findElement");
function findElement($el) {
return $el["GUID"] == $_GLOBAL["GUID"];
}

不是一个非常优雅的解决方案......但它应该有效。
