我花了很多时间试图解决这个问题，因此非常感谢您的帮助。我发现了我的问题。我有一个prepend函数，用于添加doctype。一旦移除，一切都很好。我通过将代码移动到另一个没有前置码的开发站点找到了它，它成功了。您收到了什么错误消息？抱歉，应该包括：DataTables警告（table id='example'）：DataTables警告：无法解析来自服务器的JSON数据。这是由JSON格式错误引起的。另外，如果我将json输出保存为文本文件，它将非常有效。反斜杠不能解决问题，既然响应是有效的json，为什么还需要反斜杠呢？从文本文件读取时，没有doctype头，并且接受json。服务器的输出包括doctype（见上文）。我相信我需要在PHP或Apache2中抑制doctype，但还没有找到这样做的方法。
