PHP、MySql - 旧日历不显示每月 10 天以下的事件

Question

我正在使用 David Walsh PHP 日历，经过一些修改后它再次完美运行，但我有一个无法解决的问题，每个月 10 日之前的事件不会显示...

这是几个月前的问题，但我无法解决这个问题。这是 INT 的问题，不能是“01”或“02”，但总是“1”和“2”

您可以在 www.proxin.nl/nologin/ 处查看日历，2014年10月9日至10日有事件，代码如下，您能给我一个正确的方向吗？

谢谢， 丹尼斯

就像你说的，月份和日期需要前导零。对我来说，它看起来像这条线

$event_day = $year.'-'.$month.'-'.$list_day;

是导致错误的原因。 2014 年 10 月 9 日将使 $event_day 变为 2014-10-9 而不是 2014-10-09。你可以尝试这样做

$event_day = sprintf('%d-%02d-%02d', $year, $month, $list_day);

或

$event_day = date('Y-m-d', mktime(0,0,0,$month,$list_day,$year));
