Как получить первый и последний uid объекта в foreach l oop?

/ 31 марта 2020

Я хочу получить первую и последнюю итерацию uid и сохранить в базе данных. Я использую пакет webklex для извлечения писем из gmail и сохранения в локальной базе данных, в зависимости от требований, мне нужен идентификатор объекта первой и последней итерации, но не могу ничего получить вместо ошибки. Как справиться с этой ситуацией?

Ошибка:

На самом деле вам не нужно итерировать массив, чтобы получить первый и последний элементы, вы можете просто использовать: $array[0], чтобы получить первый элемент из списка и $array[count($array) - 1] для последнего элемента. .

В вашем примере:

Первый: $user_mails[0]->id Последний: $user_mails[count($user_mails) - 1]->id

Или вы можете сделать это с помощью Eloquent: 

$first = ModelName::orderBy('id')->first()->id;

$last = ModelName::orderBy('id', 'DESC')->first()->id;
