HomeBackend DevelopmentPHP Tutorial前辈们,师兄们,我在比较时间的问题上被困扰住了,特别需要你们帮助,拜托你们帮帮我!

考勤时间存储格式问题。我用的bigint,存储了时间戳。
限定:早上9点之前刷卡,5点半之后刷卡,算作没有迟到也没有早退。
刷卡签到和刷卡签退分别用了两张表:signin和signout。
遇到的问题有:
1. 我如何在用户刷卡的时候就判断他是否迟到或早退。
2. 在月末统计的时候,我如何获取他本月所有迟到和早退的记录。

关于时间的比较,感觉很头疼。还望各位前辈指点我,十分感谢。我用的thinkphp mysql。

数据表定义如下:

create table ts_user
(wxname varchar(50) not null primary key,
 name varchar(50) not null,
telnum char(11) not null unique,
email varchar(50) unique,
address varchar(100)
)ENGINE=InnoDB DEFAULT charset=utf8;

create table ts_signin
(signid int not null auto_increment primary key,
 wxname varchar(50) not null,
 date timestamp not null,
location varchar(100) not null
)DEFAULT charset=utf8;

create table ts_signout
(signid int not null auto_increment primary key,
 wxname varchar(50) not null,
 date timestamp not null,
location varchar(100) not null
)DEFAULT charset=utf8;

alter table ts_signin add foreign key (wxname) references ts_user(wxname);
alter table ts_signout add foreign key (wxname) references ts_user(wxname);

我就在这一边想一等,能得到前辈指点,感激不尽!


回复讨论(解决方案)

strtotime("2015-01-26 09:00:00");strtotime("2015-01-26 17:30:00");

时间戳不就来了么

strtotime("2015-01-26 09:00:00");strtotime("2015-01-26 17:30:00");

时间戳不就来了么


谢谢,总算有人回答了。关键是,我到每个月底的时候,需要根据本月所有签到的时间戳,得出这个月迟到的次数,这样的话,不是要把每天的9点和17:30的时间戳都生成一下了吗?

// 获取时间的小时,   H是24小时制    根据H来判断是否迟到,至于5点半的,再比较分钟就可以了吧,这样就不用每天都要生成时间戳了date('H', $timestamp)  

    	echo date('h', strtotime("2015-01-27 09:01:10")); //9点    	echo date('i', strtotime("2015-01-27 09:01:10"));//01分

记录数据的同时判断迟到和早退,并作为一个新字段保存
当天9点的时间戳:strtotime(date('Y-m-d') . ' 09:00')跟time()对比就可以了

create table ts_user(wxname varchar(50) not null primary key, name varchar(50) not null,telnum char(11) not null unique,email varchar(50) unique,address varchar(100))ENGINE=InnoDB DEFAULT charset=utf8;create table ts_signin(signid int not null auto_increment primary key, wxname varchar(50) not null, sdate int(10) not null,chidao int(1) default 0,  // 1迟到,0没有迟到 int或bool 类型都行edate int(10) not null,zaotui int(1) default 0, //1早退,0没有早退, location varchar(100) not null  // 这是干嘛的不知道)DEFAULT charset=utf8;

直接select count(chidao ) as chidaoa from  ts_user,ts_signin, where ts_signin.wxname =ts_user.wxname and (1个月的判断)
类似这个就行, 
每天加1条数据, 迟到,早退,都知道, 记得在每天晚上12点刷新, 没有签到,的,列为迟到, 或早退,插入数据段时候直接 写入chidao, 早退判断

我设置够公司的考勤机,比较复杂,还可以根据用户分部门,分时间组;但是整体来说,一个用户只可能属于一个考勤排班组。

考勤机还有一个设置,就是什么时候开始判断为上班,什么时候开始判断为下班;然后配上考勤排班里面的上下班时间,就不然判断他是否迟到或早退。

月末统计比较简单,知道获取到所有符合考勤的时间,比如你9:00上班,你就把所有上班考勤早于9:01分的考勤全部列出来了,然后循环一下日期,顺便去除放假的时间,自然而然的,迟到就出来了

随便看看,我不说话

create table ts_user(wxname varchar(50) not null primary key, name varchar(50) not null,telnum char(11) not null unique,email varchar(50) unique,address varchar(100))ENGINE=InnoDB DEFAULT charset=utf8;create table ts_signin(signid int not null auto_increment primary key, wxname varchar(50) not null, sdate int(10) not null,chidao int(1) default 0,  // 1迟到,0没有迟到 int或bool 类型都行edate int(10) not null,zaotui int(1) default 0, //1早退,0没有早退, location varchar(100) not null  // 这是干嘛的不知道)DEFAULT charset=utf8;

直接select count(chidao ) as chidaoa from  ts_user,ts_signin, where ts_signin.wxname =ts_user.wxname and (1个月的判断)
类似这个就行, 
每天加1条数据, 迟到,早退,都知道, 记得在每天晚上12点刷新, 没有签到,的,列为迟到, 或早退,插入数据段时候直接 写入chidao, 早退判断


每天12点刷新怎么刷呢,请教一下,谢谢啊!

How does PHP type hinting work, including scalar types, return types, union types, and nullable types?How does PHP type hinting work, including scalar types, return types, union types, and nullable types?Apr 17, 2025 am 12:25 AM

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values ​​and handle functions that may return null values.
