我有一个日历功能，问题是它只显示10,11和12个月之前没有显示的事件。
因此，如果我在网址上添加：
calender.php?month=01&year=2013 TO calender.php?month=09&year=2013, No events will be displayed.
但如果我这样做：
calender.php?month=10&year=2013, calender.php?month=11&year=2013 or calender.php?month=12&year=2013, these will display fine.
我找不到负责这个bug的代码部分，任何人的想法？ ：O /
以下是完整功能代码：

答案 0 :(得分：1)
问题是你做了一个月的整数，这意味着如果你有09，它将是9，因为09不是一个整数。
要解决此问题，请更改此行：
$month = (int) ($_GET['month'] ? $_GET['month'] : date('m'));
到
$month = isset($_GET['month']) ? $_GET['month'] : date('m');
