        }

    echo "Error: " .$ex->getError()->getMessage();";
}

2. GET A SPECIFIC USER (GET /users/{id | userPrincipalName})

$graphServiceClient = new GraphServiceClient($tokenRequestContext);

$userId = "<USER-ID>"; 

try {
    $user = $graphServiceClient->users()->byUserId($userId)->get()->wait();
    if ($user) {
        echo "User Principal Name: {$user->getUserPrincipalName()}<br>";

}

3. SEARCH USER BY NAME (GET /users/$search?=)

$graphServiceClient = new GraphServiceClient($tokenRequestContext);

$userId = "<USER-ID>"; 

try {
    $memberships = $graphServiceClient->users()->byUserId($userId)->transitiveMemberOf()->get()->wait();
    if ($memberships && $memberships->getValue()) {
        foreach ($memberships->getValue() as $membership) {
            $obj = $graphServiceClient->directoryObjects()->byDirectoryObjectId($membership->getId())->get()->wait();
            if ($obj && $obj->getOdataType() === '#microsoft.graph.group') {
                $group = $graphServiceClient->groups()->byGroupId($obj->getId())->get()->wait();
                if ($group) {
                    echo "Group ID: {$group->getId()}<br>";
                    echo "Group Types: " . json_encode($group->getGroupTypes()) . "<br>";
