PHP脚本会导致array_merge和usort警告。结果文件为空,php,Php,我对这件事很困惑。我的服务器上有一个PHP文件。它的编写目的是从Google日历中提取事件信息，并将结果数据写入单独的文本文件中。PHP文件在7月1日之前一直运行良好。我不确定是什么导致了这些错误，但同一个脚本正被另一个人使用（他写的，而且对他来说仍然很好），所以我很确定这不是谷歌改变的结果。以下是访问文件时返回的特定错误 `警告：array#u merge（）[function.array merge]：参数#2不是第111行/home/westfork/public_html/AppData

您是否尝试过在
addEvents
方法中输出
$events
参数中的内容

尝试执行
var\u转储（$events）在第111行之前，查看将要输入的内容


var_dump($events);
$this->events = array_merge($this->events, $events);


这将显示
$events
的完整结构，包括属性类型。如果这是通过cron作业或其他方式运行的，您可能希望将var输出到日志文件或其他方式

此外，在尝试合并之前，您最好检查
$events
是否为数组：


if (is_array($events)) {
    $this->events = array_merge($this->events, $events);
    $this->sortEvents();
}



如果你每次都应该是一个数组，你仍然应该保留这个条件，但是添加一个
else
，通过日志通知你
$events
是什么，这样你就可以在这些情况下正确地处理它。
我不想这么说，但是我粘贴了提供的代码，它对我有效（感谢给定的日历地址）
parseEventsFromGoogleXML
必须失败，可能是因为连接错误、时间限制或其他原因。你需要处理这个问题。将
$events
设置为
$events=$this->parseEventsFromGoogleXML（$xml）之前的空数组，使用异常并尝试/捕获它们，在继续之前检查连接和/或XML结果，等等。确保您的服务器可以从外部处理文件。
抱歉，无法复制。至少灯不亮5.3.5请将代码精简到最基本的部分。那些渴望获得分数的人可能会投入努力，那些不太愿意的人可能会投票结束你的问题。我们非常喜欢简单的输入->最小代码->输出。在这样做的过程中，你甚至可以自己发现错误。大家好。对此很抱歉，但这些问题都无法重现的原因是，我给您的代码中显然不存在这些问题。出于某种原因，我对文件所做的任何更改（包括删除）都会反映在基于web的文件管理器中，但实际上并未应用。我不得不使用FTP来进行任何永久性的文件更改。我不确定是怎么回事，但问题已经解决了。非常感谢你们给予的帮助。很抱歉占用了你的时间。
