我正在通过 Amazon Web Services 获取内容（例如产品描述）。由于来自亚马逊的内容通常标记得很差，最终会弄乱我的网页布局。所以，我想出了一个使用 HTML Tidy 来“清理”内容的功能。
奇怪的是，当我将它与我的应用程序分开测试时，一切似乎都运行良好。但在我的应用程序（在 CodeIgniter 上运行）中，该函数似乎返回奇数字符。
下面的代码是我的测试脚本。它输出我认为我需要的东西。
在我的应用程序中，我从数据库中获取描述，对其进行清理，然后将其显示在我的网页上。例如，在清理之后，document’s（您可以在下面的示例中看到这个词）变为document’s（再次，仅在实际应用中；不在测试代码中。两个功能是相同的）。
任何想法为什么？这是我的测试功能：
