PHP时间戳常用转换

 1 //设置中国时区
 2 date_default_timezone_set(‘PRC‘);
 3 //今天的时间搓
 4 $today_start = strtotime(date(‘Y-m-d‘,time()).‘ 0:0:0‘);
 5 $today_end  = strtotime(date(‘Y-m-d‘,time()).‘ 23:59:59‘);
 6 //昨天的时间戳
 7 $yesterday_start = strtotime(‘-1 day‘.‘ 0:0:0‘);
 8 $yesterday_end = strtotime(‘-1 day‘.‘ 23:59:59‘);
 9 //查看上个月日期
10 $first_day_of_month = date(‘Y-m‘,time()).‘-01 00:00:01‘;
11 $t = strtotime($first_day_of_month);        
12 date(‘Y-m‘,$t);
13 date(‘Y-m‘,strtotime(‘- 1 month‘,$t));
14 date(‘Y-m‘,strtotime(‘- 2 month‘,$t));
15 
16 //获取时间戳
17 方法一：
18 $yesterday_s = mktime(0,0,0,date(‘m‘),date(‘d‘)-1,date(‘Y‘));//昨天开始的时间搓
19 $yesterday_e = mktime(23,59,59,date(‘m‘),date(‘d‘)-1,date(‘Y‘));//昨天结束的时间搓
20 
21 $tenday_s = mktime(0,0,0,date(‘m‘),date(‘d‘)-10,date(‘Y‘));//10天前开始的时间戳
22 $tenday_e = mktime(23,59,59,date(‘m‘),date(‘d‘)-10,date(‘Y‘));//10天前结束的时间戳
23     
24 //方法二：
25 $yesterday_s = strtotime(date("Y-m-d",strtotime("-10 day")).‘ 0:0:0‘); //10天前开始的时间戳
26 $yesterday_e = strtotime(date("Y-m-d",strtotime("-10 day")).‘ 23:59:59‘);//10天前结束的时间戳
27     
28 //方法三：
29 $day = $_REQUEST[‘day‘];//需要统计的日期
30 $time_s = strtotime($day.‘ 0:0:0‘);
31 $time_e = strtotime($day.‘ 23:59:59‘);
32 
33 //获取本周一的时间戳
34 strtotime(date("Y-m-d",strtotime("-1 week Monday")));
35 
36 //获取今日开始时间戳和结束时间戳
37 $beginToday = mktime(0,0,0,date(‘m‘),date(‘d‘),date(‘Y‘)); 
38 $endToday = mktime(0,0,0,date(‘m‘),date(‘d‘)+1,date(‘Y‘))-1; 
39 
40 //获取昨日起始时间戳和结束时间戳
41 $beginYesterday = mktime(0,0,0,date(‘m‘),date(‘d‘)-1,date(‘Y‘)); 
42 $endYesterday = mktime(0,0,0,date(‘m‘),date(‘d‘),date(‘Y‘))-1; 
43 
44 //获取本周起始时间戳和结束时间戳 
45 $beginThisweek = mktime(0,0,0,date(‘m‘),date(‘d‘)-date(‘w‘)+1,date(‘y‘));
46 $endThisweek = time();  
47 
48 //获取上周起始时间戳和结束时间戳  
49 $beginLastweek = mktime(0,0,0,date(‘m‘),date(‘d‘)-date(‘w‘)+1-7,date(‘Y‘));  
50 $endLastweek = mktime(23,59,59,date(‘m‘),date(‘d‘)-date(‘w‘)+7-7,date(‘Y‘)); 
51 
52 //获取本月起始时间戳和结束时间戳  
53 $beginThismonth = mktime(0,0,0,date(‘m‘),1,date(‘Y‘));
54 $endThismonth = mktime(23,59,59,date(‘m‘),date(‘t‘),date(‘Y‘));
55 
56  //上个月的起始时间:  
57 $begin_time = strtotime(date(‘Y-m-01 00:00:00‘,strtotime(‘-1 month‘)));  
58 $end_time = strtotime(date("Y-m-d 23:59:59", strtotime(-date(‘d‘).‘day‘)));  
59 
60 $begin_year = strtotime(date("Y",time())."-1"."-1"); //本年开始  
61 $end_year = strtotime(date("Y",time())."-12"."-31"); //本年结束 
62 
63 //现在的时间到第二天凌晨相差的时间戳  
64 $time = (strtotime(date(‘Y-m-d‘))+3600*24) - time() ;
