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"
