I only came into contact with redis and related things because of work needs. The result is as follows:
Part of the code is as follows
$newsRedis = Redis::get('news_'.$id);

    if ($newsRedis) return $newsRedis;

    $re = NewNotice::select('community', 'title', 'created_at', 'content', 'initiator', 'img')->where('id', '=', $id)->get();

    $change = NewNotice::where('id', '=', $id)->update([
        'state' => '1'
    ]);
    if (!$change) return 'NOTICE_ERROR';

// dd($change);

    Redis::set('news_'.$id,$re);
    Redis::expire('news_'.$id,10);
    return $re;
}

It turned out that there was an escape slash before each symbol

The following is the result of my direct return $re

Why does this happen? How can I avoid escaping?
