In this paper, an example is given to describe the implementation of php to obtain the time of recent days and months. Share it for your reference, as follows:

<?php
date_default_timezone_set('Asia/Shanghai');
echo " Today :".date("Y-m-d H:i:s")."<br>";
echo " Yesterday :".date("Y-m-d",strtotime("-1 day")), "<br>";
echo " Tomorrow :".date("Y-m-d",strtotime("+1 day")). "<br>";
echo "1 Week after :".date("Y-m-d",strtotime("+1 week")). "<br>";
echo "1 Week before :".date("Y-m-d",strtotime("-1 week")). "<br>";
echo "1 Week zero two days 4 Hours and two seconds later :".date("Y-m-d G:H:s",strtotime("+1 week 2 days 4 hours 2 seconds")). "<br>";
echo " Next week 4:".date("Y-m-d",strtotime("next Thursday")). "<br>";
echo " Last week 1:".date("Y-m-d",strtotime("last Monday"))."<br>";
echo "1 Months ago :".date("Y-m-d",strtotime("last month"))."<br>";
echo "1 Months later :".date("Y-m-d",strtotime("+1 month"))."<br>";
echo "10 Years later :".date("Y-m-d",strtotime("+10 year"))."<br>";
echo '<hr/>';
//php Get today's start and end timestamps 
$beginToday=mktime(0,0,0,date('m'),date('d'),date('Y'));
$endToday=mktime(0,0,0,date('m'),date('d')+1,date('Y'))-1;
echo " Today start timestamp and end timestamp ",' Start: ',$beginToday,' End: ',$endToday,'<br/>';
echo " Start time today :",date("Y-m-d H:i:s",$beginToday),'<br/>';
echo " End of the day :",date("Y-m-d H:i:s",$endToday),'<br/>';
echo '<hr/>';
//php Get the start and end timestamps of yesterday 
$beginYesterday=mktime(0,0,0,date('m'),date('d')-1,date('Y'));
$endYesterday=mktime(0,0,0,date('m'),date('d'),date('Y'))-1;
echo " Yesterday start timestamp and end timestamp ",' Start: ',$beginYesterday,' End: ',$endYesterday,'<br/>';
echo " Yesterday's start time :",date("Y-m-d H:i:s",$beginYesterday),'<br/>';
echo " Yesterday's end time :",date("Y-m-d H:i:s",$endYesterday),'<br/>';
echo '<hr/>';
//php Get the last week's start and end timestamps 
$beginLastweek=mktime(0,0,0,date('m'),date('d')-date('w')+1-7,date('Y'));
$endLastweek=mktime(23,59,59,date('m'),date('d')-date('w')+7-7,date('Y'));
echo " Last week start timestamp and end timestamp ",' Start: ',$beginLastweek,' End: ',$endLastweek,'<br/>';
echo " Last week's start time :",date("Y-m-d H:i:s",$beginLastweek),'<br/>';
echo " End of last week :",date("Y-m-d H:i:s",$endLastweek),'<br/>';
echo '<hr/>';
//php Get the start and end timestamps of this month 
$beginThismonth=mktime(0,0,0,date('m'),1,date('Y'));
$endThismonth=mktime(23,59,59,date('m'),date('t'),date('Y'));
echo " Start and end timestamps of this month ",' Start: ',$beginThismonth,' End: ',$endThismonth,'<br/>';
echo " Start time of this month :",date("Y-m-d H:i:s",$beginThismonth),'<br/>';
echo " End of this month :",date("Y-m-d H:i:s",$endThismonth),'<br/>';
?>
