在Laravel 5.7中，你可以使用insertUsing方法。

$query = [];
foreach($oXML->results->item->item as $oEntry){
    $date = date("Y-m-d H:i:s")
    $query[] = "('{$oEntry->firstname}', '{$oEntry->lastname}', '{$date}')";
}

Builder::insertUsing(['first_name', 'last_name', 'date_added'], implode(', ', $query));

$start_date = date('Y-m-d h:m:s');        
        $end_date = date('Y-m-d h:m:s', strtotime($start_date . "+".$userSubscription['duration']." months") );
        $user_subscription_array = array(
          array(
            'user_id' => $request->input('user_id'),
            'user_subscription_plan_id' => $request->input('subscription_plan_id'),
            'name' => $userSubscription['name'],
            'description' => $userSubscription['description'],
            'duration' => $userSubscription['duration'],
            'start_datetime' => $start_date,
            'end_datetime' => $end_date,
            'amount' => $userSubscription['amount'],
            'invoice_id' => '',
            'transection_datetime' => '',
            'created_by' => '1',
            'status_id' => '1', ),
array(
            'user_id' => $request->input('user_id'),
            'user_subscription_plan_id' => $request->input('subscription_plan_id'),
            'name' => $userSubscription['name'],
            'description' => $userSubscription['description'],
            'duration' => $userSubscription['duration'],
            'start_datetime' => $start_date,
            'end_datetime' => $end_date,
            'amount' => $userSubscription['amount'],
            'invoice_id' => '',
            'transection_datetime' => '',
            'created_by' => '1',
            'status_id' => '1', )
        );
        dd(UserSubscription::insert($user_subscription_array));

UserSubscription是我的模型名。 如果成功插入否则返回“false”，则返回“true”。

不管是谁在读这篇文章，请检查createMany()方法。

/**
 * Create a Collection of new instances of the related model.
 *
 * @param  array  $records
 * @return \Illuminate\Database\Eloquent\Collection
 */
public function createMany(array $records)
{
    $instances = $this->related->newCollection();

    foreach ($records as $record) {
        $instances->push($this->create($record));
    }

    return $instances;
}

问题解决了…修改迁移表

$table->timestamp('created_at')->nullable()->useCurrent();

解决方案:

Schema::create('spider_news', function (Blueprint $table) {
    $table->bigIncrements('id');
    $table->string('source')->nullable();
    $table->string('title')->nullable();
    $table->string('description')->nullable();
    $table->string('daterss')->nullable();

    $table->timestamp('created_at')->useCurrent();
    $table->timestamp('updated_at')->useCurrent();
});

也许更Laravel的解决这个问题的方法是使用一个集合，并利用时间戳将它与模型循环插入。

<?php

use App\Continent;
use Illuminate\Database\Seeder;

class InitialSeeder extends Seeder
{
    /**
     * Run the database seeds.
     *
     * @return void
     */
    public function run()
    {
        collect([
            ['name' => 'América'],
            ['name' => 'África'],
            ['name' => 'Europa'],
            ['name' => 'Asia'],
            ['name' => 'Oceanía'],
        ])->each(function ($item, $key) {
            Continent::forceCreate($item);
        });
    }
}

编辑:

抱歉我误会了。对于批量插入，这可能会有帮助，也许有了这个，你可以做出很好的种子和优化他们一点。

<?php

use App\Continent;
use Carbon\Carbon;
use Illuminate\Database\Seeder;

class InitialSeeder extends Seeder
{
    /**
     * Run the database seeds.
     *
     * @return void
     */
    public function run()
    {
        $timestamp = Carbon::now();
        $password = bcrypt('secret');

        $continents = [
            [
                'name' => 'América'
                'password' => $password,
                'created_at' => $timestamp,
                'updated_at' => $timestamp,
            ],
            [
                'name' => 'África'
                'password' => $password,
                'created_at' => $timestamp,
                'updated_at' => $timestamp,
            ],
            [
                'name' => 'Europa'
                'password' => $password,
                'created_at' => $timestamp,
                'updated_at' => $timestamp,
            ],
            [
                'name' => 'Asia'
                'password' => $password,
                'created_at' => $timestamp,
                'updated_at' => $timestamp,
            ],
            [
                'name' => 'Oceanía'
                'password' => $password,
                'created_at' => $timestamp,
                'updated_at' => $timestamp,
            ],
        ];

        Continent::insert($continents);
    }
}

雄辩::insert是正确的解决方案，但它不会更新时间戳，所以你可以像下面这样做

 $json_array=array_map(function ($a) { 
                        return array_merge($a,['created_at'=> 
                                            Carbon::now(),'updated_at'=> Carbon::now()]
                                           ); 
                                     }, $json_array); 
 Model::insert($json_array);

其思想是在插入之前在整个数组上添加created_at和updated_at
