ThinkPHP中获取指定日期后工作日的具体日期方法
在本文中,我们给大家带来的是关于ThinkPHP中获取指定日期后工作日的具体日期的方法以及实例代码,有需要的朋友们学习下。
思路:
1、获取到查询年份内所有工作日数据数组
2、获取到查询开始日期在工作日的索引
3、计算需查询日期索引
4、获得查询日期
- /*创建日期类型记录表格*/
- CREATE TABLE `tb_workday` (
- `did` int(11) NOT NULL AUTO_INCREMENT,
- `exact_date` varchar(32) NOT NULL COMMENT '具体日期:格式date("Ymd");(20170205)',
- `date_year` varchar(32) NOT NULL COMMENT '具体日期:格式date("Y");(2017)',
- `date_type` tinyint(2) NOT NULL COMMENT '日期类型:0、工作日;1、特殊工作日;2、法定节假日',
- PRIMARY KEY (`did`)
- ) ENGINE=InnoDB AUTO_INCREMENT=829 DEFAULT CHARSET=utf8 COMMENT='各年工作日&法定节假日数据'

- $month = sprintf('%02d', $arr[1]);
- //日,输出2位整型,不够2位右对齐

- //时分秒默认赋值为0;
- $hour = $minute = $second = 0;
- //转换成时间戳

- //获取数字型星期几
