PHP Development Notes-Commonly used date acquisition methods in day/week operations_PHP Tutorial

This Monday
echo date('Y-m-d',(time()-((date('w')==0?7:date('w'))-1) *24*3600)); //w is the numeric form of the day of the week, here 0 is Sunday

This Sunday

echo date('Y-m-d',(time()+(7-(date('w')==0?7:date('w')))*24*3600)); // Also use w to calculate based on the number of days related to Sunday

Last Monday

echo date('Y-m-d',strtotime('-1 monday', time())); //No matter what day it is, -1 monday is the previous valid weekday

Last Sunday

echo date('Y-m-d',strtotime('-1 sunday', time())); //The last valid Sunday, the same applies to other weeks

One day of this month

echo date('Y-m-d',strtotime(date('Y-m', time()).'-01 00:00:00')); //Generate directly from strtotime

Last day of this month

echo date('Y-m-d',strtotime(date('Y-m', time()).'-'.date('t', time()).' 00:00:00') ); //t is the number of days in the month, from 28 to 31 days

The first day of last month

echo date('Y-m-d',strtotime('-1 month', strtotime(date('Y-m', time()).'-01 00:00:00'))); // On the first day of this month, strtotime will be directly increased and subtracted by one month

The last day of the previous month

echo date('Y-m-d',strtotime(date('Y-m', time()).'-01 00:00:00')-86400); //One day minus one day of this month is It’s the last day of last month
