Найти значение в вложенном ассоциативном массиве

Question

Я хочу получить значение «GUID» со значением «SamAccountName». т. е. у меня есть только значение pf 'SamAccountName', и я хотел бы получить значение «GUID» для этой части массива.

Это было первоначально объект StdClass, но я использовал json_decode (json_encode ($ OBJ), правда), чтобы преобразовать в ассоциативный массив.

Answer 1

Похоже, вы хотите получить часть GUID для значения «SamAccountName». Используйте цикл Еогеасп:

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

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

Answer 2

Вот пример функции, которую вы можете использовать. Это предполагает, что будет только один объект с SamAccountName, который вы поставте в массиве (он просто использует первый, который он находит). Он возвращает GUID соответствующего массива и false, если он не может найти массив с соответствующим именем SamAccountName.

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

Answer 3

Вы можете использовать простой цикл, чтобы принести его

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

Answer 4

это то, что вы ищете?

function findBySam($arrayList, $sam) { 

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

Answer 5

Вы можете использовать array_filter функцию из PHP: http://php.net/manual/en/function.array-filter.php

пример:

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

Не очень элегантное решение ... но он должен работать.
