// To calculate yesterday's time, we use: 

date("Ymd",time()-3600);

// Generate yesterday's time 

date("Ymd",strtotime('yesterday'));

date("Ymd",strtotime('-1 day'));

// Generate the time of the day before yesterday 

date("Ymd",strtotime('yesterday -1 day'));

date("Ymd",strtotime('-2 day'));

// Generate 3 The time after days 

date("Ymd",strtotime('+3 day'));

// Generate 1 Three months ago 

date("Ymd",strtotime('-1 month'));

// Generate the last of next month 1 The time of days 

date("Ymd",strtotime('last day of next month'));

// The week of next week 1

date("Ymd",strtotime('next monday'));
