echo strtotime(date('Y-m-d'));
获取明天凌晨的时间戳
代码：echo strtotime(date('Y-m-d',strtotime('+1 day')));
附上测试代码：
echo strtotime('2012-11-2');
echo strtotime('2012-11-2 00:00:00');
echo strtotime(date('Y-m-d')),'
';
echo date('Y-m-d H:i:s',strtotime(date('Y-m-d')));
echo strtotime(date('Y-m-d',strtotime('+1 day')));
echo ( strtotime(date('Y-m-d',strtotime('+1 day'))) - strtotime(date('Y-m-d')) )/3600;
其它参考代码：
echo "一周后:".date("Y-m-d",strtotime("+1 week"));
echo "一周零两天四小时两秒后:".date("Y-m-d G:H:s",strtotime("+1 week 2 days 4 hours 2 seconds"));
echo "下个星期四:".date("Y-m-d",strtotime("next Thursday"));
echo "上个周一:".date("Y-m-d",strtotime("last Monday"));
echo "一个月前:".date("Y-m-d",strtotime("last month"));
echo "一个月后:".date("Y-m-d",strtotime("+1 month"));
echo "十年后:".date("Y-m-d",strtotime("+10 year"));
