You can use INNER JOIN in SQL to connect two tables on a shared value. 您可以在SQL中使用INNER JOIN在一个共享值上连接两个表。

I'm assuming that the value in unique_id is the column both tables have in common. 我假设unique_id中的值是两个表共有的列。

If you change your database query to: 如果您将数据库查询更改为：

SELECT 
    player.unique_id,  
    player.username,
    combat.kills,
    combat.deaths
FROM 
    player
INNER JOIN 
    combat ON player.unique_id = combat.unique_id
ORDER BY 
    player.unique_id DESC

This query will join both tables where the columns unique_id has the same value. 此查询将unique_id两个表，其中unique_id列的值相同。

Now you can echo the content just like before: 现在，您可以像以前一样回显内容：

<td>'.$row["username"].'</td>  
<td>'.$row["unique_id"].'</td>
<td>'.$row["kills"].'</td>
<td>'.$row["deaths"].'</td>
