Find a value in nested associative array

Question

I want to get the value of 'GUID' with the value of 'SamAccountName'. i.e. I only have the value pf 'SamAccountName' and I would like to get the value of 'GUID' for that part of the array.

This was originally a stdClass object but I used json_decode(json_encode($obj), true) to convert to an associative array.

just to get this right: you have the SamName e.g. mario and you want a function which returns the guid of the same array you know the SamName is mario? — Soundz

Yes, that's what I need. So for example csliney_playgroundla should return 71224be8-1b8b-46e7-97ef-2cd873bf9b7f — Grug

Sounds like you want to get the GUID portion for the value of 'SamAccountName'. Use a foreach loop:

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

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

Thanks a lot. Was much simpler than I thought.

You can use a simple loop to fetch it

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

is this what you are looking for?

function findBySam($arrayList, $sam) {

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

Here is an example of a function that you could use. This assumes that there will be only one object with the SamAccountName that you supply in the array (it just uses the first one that it finds). It returns the GUID of the matching array and false if it cannot find an array with a matching SamAccountName.

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

good catch. that'll teach me to try to refactor my code in the SO editor!

You can use array_filter function of php: http://php.net/manual/en/function.array-filter.php

example:

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

Not a very elegant solution... but it should work.
