静态 times 方法通过调用给定次数的回调函数来创建新集合：

$collection = Collection::times(10, function ($number) {
    return $number * 9;
});

$collection->all();

// [9, 18, 27, 36, 45, 54, 63, 72, 81, 90]Copy

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 Category::factory()->create(['name' => "Category No. $number"]);
});

$categories->all();

/*
    [
        ['id' => 1, 'name' => 'Category No. 1'],
        ['id' => 2, 'name' => 'Category No. 2'],
        ['id' => 3, 'name' => 'Category No. 3'],
    ]
*/
