# times方法 通过回调在给定次数内创建一个新的集合。 ``` $collection = Collection::times(10, function ($number) { return $number * 9; }); $collection->all(); // [9, 18, 27, 36, 45, 54, 63, 72, 81, 90] ``` 使用这个方法可以与工厂结合使用创建出 `Eloquent` 模型 ``` $categories = Collection::times(3, function ($number) { return factory(Category::class)->create(['name' => 'Category #'.$number]); }); $categories->all(); /* [ ['id' => 1, 'name' => 'Category #1'], ['id' => 2, 'name' => 'Category #2'], ['id' => 3, 'name' => 'Category #3'], ] */ ```
