echo date("Y-m-d H:i:s", mktime(23,59,59,date("m"),date("d")-date("w")+7,date("Y"))); //2020-03-15 23:59:59

2.获取上周开始和结束的日期:

echo date('Y-m-d H:i:s', mktime(0,0,0,date('m'),date('d')-date('w')+1-7,date('Y'))); //2020-03-02 00:00:00

echo date('Y-m-d H:i:s', mktime(23,59,59,date('m'),date('d')-date('w')+7-7,date('Y'))); //2020-03-08 23:59:59

3.获取本月开始和结束的日期:
