php教程 strtotime()总结明天与钦命日期之造化

example:
include_once '/class/calendar.class.php';
$simple_example = new calendar();
print($simple_example->output_calendar());

$date1 = strtotime('二零一一-04-30'); //把日期调换到时间戳
$date2 = time(); //取当前光阴的年月戳

*/

$nowtime=strftime("%y年-%m月-%d日 ",$date2); //格式化出口日期

 代码如下

$days=round(($date1-$date2)/3600/24); //四舍五入
