Как удалить дублирующиеся строки в коллекции в зависимости от двух ключей вместе

0 голосов
/ 21 марта 2020

У меня есть база данных, и мне нужно удалить дублирующиеся строки в зависимости от двух ключей вместе 

$messages = DB::table('users_mailbox')->where('msg_to', $username)->orderBy('id', 'desc')->paginate(10);

Я пытался 

$messages = $messages->unique('msg_from','ad_id);

Это мой ответ 

    +"id": 39
    +"ad_id": "2866527370"
    +"msg_from": "aliman"
    +"msg_to": "Haitham  Hmaserv"
    +"email": "amr@gmail.com"
    +"show_email": 1
    +"phone": "01002445900"
    +"show_phone": 1
    +"subject": "Re: akls;fdjl fa;dslkjf"
    +"message": "sadklfjlkads ;jfkladjf"
    +"is_read": 0
    +"created_at": "2020-03-15 00:15:53"
    +"updated_at": "2020-03-15 00:15:53"

Но результат неверный.

Вы не можете использовать несколько клавиш. unique имеет только 2 параметра: $key и $strict. 

/**
 * Return only unique items from the collection.
 *
 * @param  string|callable|null  $key
 * @param  bool  $strict
 * @return static|\Illuminate\Support\Collection
 */
public function unique($key = null, $strict = false)
{
    if (! is_null($key)) {
        return parent::unique($key, $strict);
    }

    return new static(array_values($this->getDictionary()));
}

Вы можете передать свой собственный обратный вызов, чтобы определить уникальность элемента: 

$messages = $messages->unique(function ($item) {
    return $item['msg_from'] . $item['ad_id'];
});

Я рекомендую использовать DISTINCT вместо unique метод сбора .
