我有一些麻烦弄清楚到底是什么是错误的我的代码，我似乎无法从我的数据库检索数据。
我在php检查器上绝对没有错误，它以前在测试之前工作过，然后我扩展了代码以具有更好的搜索模式，现在通过编码的一半突然停止工作，我无法找出问题。
我知道连接到我的数据库工作，因为我使用它为我的网站的另一部分。
对此事的任何帮助都将非常感激。

感谢大家指出我代码中的缺陷，如果我没有在这里发布，我不会知道这一点，直到我的数据库被攻击，我现在正在努力修复它们。我发现我的问题不是代码，虽然它更多地与我缺乏知识有关，你看到测试后，我将我的dbconnection参数移动到一个ini文件，并将它们存储在我的根文件夹之外，以保证它的安全，在那里，dbconnection变量然后成为一个局部变量，基本上在变量存储的文件夹之外不可用。解决方案很简单，我只是把我的搜索引擎移动到相同的文件夹
