Question

我有以下脚本和网站http://cacrochester.com，有时右侧边栏的内容会加载，有时则不会。我想如果它是你在页面上的前几次，它会说没有安排任何事件。

我完全不知道为什么会这样。数据库中的数据没有变化。

如果您需要我发布更多代码，请告诉我。

感谢您的帮助！

当你执行$startDate >= $today时，你试图比较两个数组，这不是一个好主意。只需使用简单的时间戳，它应该可以正常工作：

$startDate = $result['start_date'];
$today = strtotime('today');

此外，我不确定这是否是拼写错误：current($result) == end($result)，但不应该是$results，这是数组名称吗？

有时内容会加载，有时则不会
