mysql - Laravel，插入多行而不使用foreach

Question

$input['activities'] = array(3,2,5);

foreach($input['activities'] as $activity_id){

    $user_activities = new User_activities;

    $user_activities->activity_id = $activity_id;

    $user_activities->user_id = Auth::id();

    $user_activities->save();

}

是否可以用一行脚本来为 Laravel 中的每个语句执行上述保存操作？而不是在 foreach 中进行保存，是否可以在一行中进行保存？

Answer 1

只需将数组的数组传递给 Eloquent::insert():

$data = [];

foreach($input['activities'] as $activity_id) {
    $data[] = [
        'activity_id' => $activity_id,
        'user_id' => Auth::id()
    ];
}

Coder::insert($data);
