我有一个简单的Laravel预订系统，我想计算我的预订价格。首先，我需要找到我的记录（time_from）和（time_to）之间的区别，然后我认为我需要将此数据保存到数据库中并相乘每晚的房费上怎么办？如果您有一个更简单的解决方案，请告诉我。我是Laravel的新手，等待您的帮助。
它是我的BookingsController：

和我的数据库
public function up()
{
if(! Schema::hasTable('bookings')) {
Schema::create('bookings', function (Blueprint $table) {
$table->increments('id');
$table->datetime('time_from')->nullable();
$table->datetime('time_to')->nullable();
$table->integer('diff_days')->nullable();
$table->text('additional_information')->nullable();
$table->string('first_name');
$table->string('last_name');
$table->string('address')->nullable();
$table->string('phone')->nullable();
$table->string('email');
$table->timestamps();
$table->softDeletes();
$table->index(['deleted_at']);
});
}
}
您可能想减去时间戳，因为知道time_to总是高于time_from，所以我们将继续下一步：
// Note: $booking is a defined object of Booking model
($booking->time_to->timestamp) - ($booking->time_from->timestamp)
据您所见，我们将得到一个整数作为这两个时间戳的减法值。您可以将结果除以86400（一天的秒数），以获取预订天数。
您可能想添加一个函数，该函数将在您希望收集差额的任何时候使用所提及的代码并返回预订的天数，或者可以将其存储到数据库中。
