这个不行。要加自然月,有的月分28天。有的31天
$s='2013-07-31';
echo date("Y-m-d",strtotime("$s+1 month"));
呵呵,想当然了
echo date("Y-m-d\n",strtotime("$s+7 month"));得到 2014-03-03
select adddate('2013-07-31', INTERVAL 7 month)得到 2014-02-28
mktime其实也可以达到要求
$t = '2013-07-31';echo date("Y-m-d",mktime(0,0,0,date("m") + 12,date("d") , date("Y"))).'
';echo date("Y-m-d",mktime(0,0,0,date("m") + 3,date("d") , date("Y"))).'
';echo date("Y-m-d",mktime(0,0,0,date("m") + 1,date("d") , date("Y"))).'
';
2014-07-312013-10-312013-08-31
$t = '2013-07-31';echo date("Y-m-d",mktime(0,0,0,date("m") + 2,date("d") , date("Y")));
