echo nbsp strtotime week

php中挺好用的strtotime方法
  在PHP中,经常要对日期进行计算,比如要计算一个月前的日期,那么其实最快的方法
是用strtotime,其功能很丰富,如下:

echo strtotime("now"), "\n";echo strtotime("10 September 2000"), "\n";echo strtotime("+1 day"), "\n";echo strtotime("+1 week"), "\n";echo strtotime("+1 week 2 days 4 hours 2 seconds"), "\n";echo strtotime("next Thursday"), "\n";echo strtotime("last Monday"), "\n";
Copy after login

  看到没 +1 day  +1 week,马上求出1天后,1个星期后的日期了,
求1个月前,可以:
echo date('Y-m-d', strtotime('1 month ago'))

  因此,判断是否一个月前,可以
if  strtotime($my_date)
