Carbon生成年度月份起止时间

用于按月份统计数据,适用于日期类型字段的区间查询。

/**
 * 获取各个月份起止时间.
 *
 * @param number $number 获取月份数,留空默认为当前月份
 * @param number $moreNumber 额外月份(大于当前月份)
 *
 * 返回值示例: array:3 [▼
  0 => array:3 [▼
    "name" => "1月"
    "start" => "2022-01-01"
    "end" => "2022-01-31"
  ]
  1 => array:3 [▼
    "name" => "2月"
    "start" => "2022-02-01"
    "end" => "2022-02-28"
  ]
  2 => array:3 [▼
    "name" => "3月"
    "start" => "2022-03-01"
    "end" => "2022-03-31"
  ]
]
