PHP 结合MYSQL简单的实现了Todo List 功能
2024-06-11 07:45:12
具体功能如下：
1、增加、修改、删除及标记任务完成；
2、历时任务查看；
3、任务优先级 ；
效果图：

SQL创建脚本：
2 CREATE TABLE IF NOT EXISTS `todo` (
`id` int(11) NOT NULL AUTO_INCREMENT,
3 `content` varchar(500) NOT NULL,
4 `op_date` date NOT NULL,
5 `status` int(1) NOT NULL,
6 `complete_date` date NOT NULL,
7 `level` int(1) NOT NULL,
8 PRIMARY KEY (`id`)
9 ) ENGINE=InnoDB DEFAULT CHARSET=utf8 AUTO_INCREMENT=18 ;
`id` int(11) NOT NULL AUTO_INCREMENT,
3 `content` varchar(500) NOT NULL,
4 `op_date` date NOT NULL,
5 `status` int(1) NOT NULL,
6 `complete_date` date NOT NULL,
7 `level` int(1) NOT NULL,
8 PRIMARY KEY (`id`)
9 ) ENGINE=InnoDB DEFAULT CHARSET=utf8 AUTO_INCREMENT=18 ;
就花了一个多小时做的，只实现了基本功能，连注释也没来得及写，其实也就是CURD功能 :)
