Laravel检查，如果记录新创建的

代码示例

laravel8检查，如果记录存在

        
		$subscription_count = DB::table('subscriptions')->where('pid_user',$pid_user)->count();

        //check if any subscription plan exists
        if($subscription_count == 0)
        { 
          //record does not exist 
        }else{
          //record exists
        }

laravel检查，如果雄辩的只是创造了

$item = Item::firstOrCreate(['title' => 'Example Item']);

if ($item->wasRecentlyCreated === true) {
    // item wasn't found and have been created in the database
} else {
    // item was found and returned from the database
}
