使用php填充html表

Question

I need to populate a table with data regarding 10 countries using a .php and .html file. 我需要使用.php和.html文件填充有关10个国家/地区的数据的表格。 I have downloaded XAMPP (7.1.8) I am working on a MacBook Pro 2012 running Sierra (can not get XAMPP-VM to run - get a signal killed error message on start up). 我已经下载了XAMPP（7.1.8），我正在运行Sierra的MacBook Pro 2012上运行（无法运行XAMPP-VM-启动时收到信号消失的错误消息）。

I have created the database testdb in MySql and coded the database.html file and the getuser.php file as below and saved them to the htdocs folder on the server - but when it renders, it isn't picking up the xml file or the data within. 我已经在MySql中创建了数据库testdb，并按如下所示对database.html文件和getuser.php文件进行了编码，并将它们保存到服务器上的htdocs文件夹中-但是在呈现时，它并没有选择xml文件或内的数据。

I believe the problem is either on line 46 in the php or line 36 in the html, but I don't know enough about php to to know how to change it to make it work. 我认为问题出在php的第46行或html的第36行，但我对php的了解还不足以知道如何更改它以使其正常工作。 Any help would be much appreciated, 任何帮助将非常感激，

Thanks 谢谢

Answer 1

The Problem is that you fetch an Array instead of an Assoziation. 问题在于您获取的是数组而不是关联。 Use mysqli_fetch_assoc(). 使用mysqli_fetch_assoc（）。 Then you can access the Array like you do. 然后，您可以像访问阵列一样访问该数组。

while ($row = mysqli_fetch_assoc($result)) 而（$ row = mysqli_fetch_assoc（$ result））

and close the first table tag. 并关闭第一个表格标签。
