如何用PHP中的mktime函数获取开始和结束时间
php 获取今日、昨日、上周、本月的起始时间戳和结束时间戳的方法,主要使用到了 php 的时间函数 mktime()。
mktime函数用法如下:mktime(hour,minute,second,month,day,year,is_dst)
参数描述
hour 可选。规定小时。
minute 可选。规定分钟。
second 可选。规定秒。
month 可选。规定用数字表示的月。
day 可选。规定天。
year 可选。规定年。在某些系统上,合法值介于 1901 - 2038 之间。不过在 PHP 5 中已经不存在这个限制了。
is_dst 可选。如果时间在日光节约时间(DST)期间,则设置为1,否则设置为0,若未知,则设置为-1。(自 PHP 5.1.0 起,本参数已被废弃。应该使用新的时区处理特性来替代。)
例子:今日、昨日、上周、本月的起始时间戳和结束时间戳
1 //获取今日开始时间戳和结束时间戳
2 $start = mktime(0,0,0,date('m'),date('d'),date('Y'));
3 $end = mktime(0,0,0,date('m'),date('d')+1,date('Y'))-1;
4 //获取昨日起始时间戳和结束时间戳
5 $beginYesterday = mktime(0,0,0,date('m'),date('d')-1,date('Y'));
6 $endYesterday = mktime(0,0,0,date('m'),date('d'),date('Y'))-1;
7 //获取上周起始时间戳和结束时间戳
8 $beginLastweek = mktime(0,0,0,date('m'),date('d')-date('w')+1-7,date('Y'));
9 $endLastweek = mktime(23,59,59,date('m'),date('d')-date('w')+7-7,date('Y'));
10 //获取本月起始时间戳和结束时间戳
11 $beginThismonth=mktime(0,0,0,date('m'),1,date('Y'));
12 $endThismonth=mktime(23,59,59,date('m'),date('t'),date('Y'));
