Application scenario

Count the number of articles published by a person according to today, yesterday, last week, this week, and this month

Principle analysis

Suppose there is a field in the article table to store the timestamp of article creation (cdate), For example, today (2016-11-8), then the query condition is cdate >= 2016-11-8 00:00 AND cdate

Implementation plan

According to the above analysis, it is necessary If you know today's start timestamp and end timestamp, then yesterday, last week, and this week are similar. Use PHP's mktime function to obtain the start and end timestamps.

mktime()

Syntax: mktime(hour,minute,second,month,day,year)

PHP implements data statistics functions for today, yesterday, last week, this week, and this month

Code implementation

//php获取今日开始时间戳和结束时间戳
$today_start=mktime(0,0,0,date(&#39;m&#39;),date(&#39;d&#39;),date(&#39;Y&#39;));
$today_end=mktime(0,0,0,date(&#39;m&#39;),date(&#39;d&#39;)+1,date(&#39;Y&#39;))-1;
//php获取昨日起始时间戳和结束时间戳
$yesterday_start=mktime(0,0,0,date(&#39;m&#39;),date(&#39;d&#39;)-1,date(&#39;Y&#39;));
$yesterday_end=mktime(0,0,0,date(&#39;m&#39;),date(&#39;d&#39;),date(&#39;Y&#39;))-1;
//php获取上周起始时间戳和结束时间戳
$lastweek_start=mktime(0,0,0,date(&#39;m&#39;),date(&#39;d&#39;)-date(&#39;w&#39;)+1-7,date(&#39;Y&#39;));
$lastweek_end=mktime(23,59,59,date(&#39;m&#39;),date(&#39;d&#39;)-date(&#39;w&#39;)+7-7,date(&#39;Y&#39;));
//php获取本周周起始时间戳和结束时间戳
$thisweek_start=mktime(0,0,0,date(&#39;m&#39;),date(&#39;d&#39;)-date(&#39;w&#39;+1),date(&#39;Y&#39;));
$thisweek_end=mktime(23,59,59,date(&#39;m&#39;),date(&#39;d&#39;)-date(&#39;w&#39;)+7,date(&#39;Y&#39;));
//php获取本月起始时间戳和结束时间戳
$thismonth_start=mktime(0,0,0,date(&#39;m&#39;),1,date(&#39;Y&#39;));
$thismonth_end=mktime(23,59,59,date(&#39;m&#39;),date(&#39;t&#39;),date(&#39;Y&#39;));
