用php获取本周、本月第一天与最后天时间戳。
1,获取今天的时间范围:
<?php
$start = mktime(0,0,0,date("m"),date("d"),date("Y"));
$end = mktime(0,0,0,date("m"),date("d")+1,date("Y"));
2,获取本周第一天/最后一天的时间戳
<?php
$year = date("Y");
$month = date("m");
$day = date(‘w‘);
$nowMonthDay = date("t");
$firstday = date(‘d‘) - $day;
if(substr($firstday,0,1) == "-"){
$firstMonth = $month - 1;
$lastMonthDay = date("t",$firstMonth);
$firstday = $lastMonthDay - substr($firstday,1);
$time_1 = strtotime($year."-".$firstMonth."-".$firstday);
}else{
$time_1 = strtotime($year."-".$month."-".$firstday);
}
$lastday = date(‘d‘) + (7 - $day);
if($lastday > $nowMonthDay){
$lastday = $lastday - $nowMonthDay;
$lastMonth = $month + 1;
$time_2 = strtotime($year."-".$lastMonth."-".$lastday);
}else{
$time_2 = strtotime($year."-".$month."-".$lastday);
}
3,获取本月第一天/最后一天的时间戳
<?php
$year = date("Y");
$month = date("m");
$allday = date("t");
$strat_time = strtotime($year."-".$month."-1");
$end_time = strtotime($year."-".$month."-".$allday);
计算时间差
$one = strtotime(‘2011-12-08 07:02:40‘);//开始时间 时间戳
$tow = strtotime(‘2011-12-25 00:00:00‘);//结束时间 时间戳
$cle = $tow - $one; //得出时间戳差值
$d = floor($cle/3600/24);
$h = floor(($cle%(3600*24))/3600); //%取余
$m = floor(($cle%(3600*24))600/60);
$s = floor(($cle%(3600*24))`);
echo "两个时间相差 $d 天 $h 小时 $m 分 $s 秒"
