用php获取本周,上周,本月,上月,本季度日期的代码

echo date("Ymd",strtotime("now")), "\n";

echo date("Ymd",strtotime("-1 week Monday")), "\n";

echo date("Ymd",strtotime("-1 week Sunday")), "\n";

echo date("Ymd",strtotime("+0 week Monday")), "\n";

echo date("Ymd",strtotime("+0 week Sunday")), "\n";

//date('n') 第几个月

//date("w") 本周周几

//date("t") 本月天数
