我在两个不同的项目上使用相同的服务器端代码。它在一个中工作，但在另一个中产生两个错误。这是php页面
/*
* DataTables example server-side processing script.

* Please note that this script is intentionally extremely simply to show how

* for learning.

* See http://datatables.net/usage/server-side for full details on the server-
* side processing requirements of DataTables.

这都是在自己的php页面上，所以当我调用那个php页面时，我得到了这个，

大约有5k记录。我使用的是版本1.10.5。而且无法弄清楚这笔交易是什么。除了表名和列之外，这与我在另一页上所做的相同，但在此页面上它不起作用。如果我尝试使用ajax从主页调用此函数，我也会收到错误，这就是为什么我决定调用php页面来查看我得到的内容。我注意到的最重要的事情是，在输出中我得到了输出的开头
draw":0,"recordsTotal":5342,"recordsFiltered":5342,
在我的另一页上，我只是获取表数据。
