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

Answer 1

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);

Answer 2

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);

Answer 3

is this what you are looking for?
function findBySam($arrayList, $sam) {
foreach($arrayList as $array) {
if($array['SamAccountName'] == $sam) {
return $array;
}
}
return false;
}

Answer 4

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
}

Answer 5

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.
