PHP 獲取今日、昨日、上周、本月的起始時間戳和結束時間戳的方法

主要使用到了 php 的時間函數 mktime。

官方文檔：http://kr1.php.net/manual/zh/function.mktime.php

//php獲取今日開始時間戳和結束時間戳
$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獲取本周起始時間
$beginWeek = mktime(0,0,0,date("m"),date("d")-date("w")+1,date("Y"));
$endWeek = mktime(23,59,59,date("m"),date("d")-date("w")+7,date("Y"));
//php獲取昨日起始時間戳和結束時間戳
$beginYesterday=mktime(0,0,0,date('m'),date('d')-1,date('Y'));
$endYesterday=mktime(0,0,0,date('m'),date('d'),date('Y'))-1;
//php獲取上周起始時間戳和結束時間戳
$beginLastweek=mktime(0,0,0,date('m'),date('d')-date('w')+1-7,date('Y'));
$endLastweek=mktime(23,59,59,date('m'),date('d')-date('w')+7-7,date('Y'));
//php獲取本月起始時間戳和結束時間戳
$beginThismonth=mktime(0,0,0,date('m'),1,date('Y'));
$endThismonth=mktime(23,59,59,date('m'),date('t'),date('Y'));

 

//獲取今天00:00
$todaystart = strtotime(date(‘Y-m-d’.’00:00:00′,time()));
//獲取今天24:00
$todayend = strtotime(date(‘Y-m-d’.’00:00:00′,time()+3600*24));
//統計今天注冊的用戶
$todayuser[‘create_time’] = array(between,”$todaystart,$todayend”);
$todaysum = $Users->where($todayuser)->count();


//獲取昨天00:00
$timestart = strtotime(date(‘Y-m-d’.’00:00:00′,time()-3600*24));
//獲取今天00:00
$timeend = strtotime(date(‘Y-m-d’.’00:00:00′,time()));
//統計昨天注冊的用戶
$map[‘create_time’] = array(between,”$timestart,$timeend”);
$daycount = $Users->where($map)->count();

$this->assign(“todaysum”,$todaysum);
$this->assign(“daycount”,$daycount);
