编辑：当我添加 error_reporting(-1); 我收到此错误消息：
Notice: Trying to get property of non-object in /data/22/2/145/126/2960289/user/3282682/htdocs/add.php on line 106

我正在尝试使用 Simple HTML DOM Parser (http://simplehtmldom.sourceforge.net/) 来搜索站点。它在 localhost 上运行良好，但是当我将它上传到我的主机（网络解决方案）时，一些 url 不再给出任何结果。它发生在我从 file_get_html 切换到 str_get_html 时。我不得不这样做，因为主人。你知道有什么问题吗？对于脚本的外观，我很抱歉，但我是个新手......也许你有一些关于如何压缩它的提示？脚本如下所示：
