php到日历ics脚本几乎可以正常工作。。？

我正在使用我找到的这个php-ics脚本。不久前，我为一些客户开发了活动日历。他们想要一种方法将其导出到.ics、谷歌

这是我的delima，我想。。我不确定您是否需要$start\u date、$start\u time、$end\u date、$end\u time。。我的MYSQL数据库中没有这些。。。那么我是不是应该把这些都留空白

我只有一个$date字段，我输入的日期如下：“0000-00-00”

下面是写入文件的简单php脚本：（这里是ics部分）

如您所见，我使用$date行来等于这些ics变量：$start_date、$start_time、$end_date、$end_time。。不确定这是否可以

谢谢你的帮助。。我是这方面的新手。

可能会有所帮助。谢谢，我在搜索时看到了第一个链接，但仍然是空的。我将阅读你的第二个链接。感谢您的关注。如果您正在以缩写形式“0000-00-00”存储日期，那么您需要将所有时间默认为0:00或类似的时间，因为您不存储它。
