how to get user detail like user-id by username

[NicklasWallgren]

You need to get hold of the user id, either by searching or from feed/message.

Here you have a simple search example;

$searchResult = $instagram->searchByUser('username');

if (!$searchResult->isSuccess()) {
    die($searchResult);
}

foreach ($searchResult->getUsers() as $user) {
    print_r($user);

    die();
}
