请添加不能正常工作的查询。 –

我更新了代码 – Millz

不知何故'executeQuery（）'返回false。您的查询必须无效，您可以在PHPMyAdmin（或任何您使用的）中尝试查询。 –

-1

请阅读documentation on mysqli_query()。

它告诉你：

返回FALSE失败。为成功SELECT,SHOW,DESCRIBE或EXPLAIN查询mysqli_query()将返回一个mysqli_result对象。对于其他成功的查询mysqli_query()将返回TRUE。

这意味着您的查询失败或不是SELECT，SHOW，DESCRIBE或EXPLAIN查询。

请问我应该采取哪些步骤来解决问题 – Millz

@Millz如果你给我你的代码（导致错误的代码，而不是db文件，你用来查询的实际代码），我只能帮你。 –

好的。我粘贴了代码 – Millz

我收到此错误消息。我应该采取什么措施来解决了这个问题
