Question

我正在csgo的bhop服务器中列出最佳时间的前十名。所有时间都存储在数据库中，但问题是每次用户获得新时间时都会添加新行。使用我现在的代码，它显示了所有时间的前十个列表，我希望它只显示每个用户一个结果（最好的一个）

我目前的代码：

<div id="content">
        <table cellspacing="0">
        <h1 align="center">bhop_eazy_csgo</h1>
            <tr><th>Place</th><th>Name</th><th>Time</th></tr>
            <?php
            $i = 1;
                    $con=mysqli_connect("localhost","root","*******","timer");
                    // Check connection
                    if (mysqli_connect_errno()) {
                      echo "Failed to connect to MySQL: " . mysqli_connect_error();
                    }

                    $result = mysqli_query($con,"SELECT * FROM round WHERE map = 'bhop_eazy_csgo' ORDER BY time LIMIT 0, 10");
                    while($row = mysqli_fetch_array($result)) {

                          echo "<tr><td>" . ($i) . "</td><td>" . $row['name'] . "</td> <td>" . gmdate("i:s", $row['time']) . "</td></tr>";
                          $i++;
                    }

                mysqli_close($con);
            ?>
        </table>
</div>

修改
现在它看起来像这样：

1 Wildmine 00:49
2 Wildmine 00:50
3 Wildmine 01:02
4 【J @ RR3？一点12分

我希望它看起来像这样：

1 Wildmine 00:49
2？J @ rr3？ 01:12
感谢Michael Wagner帮助我开展工作：）

$result = mysqli_query($con,"
                    SELECT DISTINCT name n, (
                        SELECT time
                        FROM round
                        WHERE map = 'bhop_eazy_csgo'
                        AND name = n
                        ORDER BY time
                        LIMIT 1
                    ) AS time
                    FROM round
                    WHERE map = 'bhop_eazy_csgo'
                    ORDER BY time
                    LIMIT 0 , 10
                    ");
                    while($row = mysqli_fetch_array($result)) {

                    echo "<tr><td>" . ($i) . "</td><td>" . $row['n'] . "</td> <td>" . gmdate("i:s", $row['time']) . "</td></tr>";
                    $i++;

}

试试这个：

SELECT DISTINCT name n, (
    SELECT time
    FROM round
    WHERE map = 'bhop_eazy_csgo'
    AND name = n
    ORDER BY time
    LIMIT 1
) AS time
FROM round
WHERE map = 'bhop_eazy_csgo'
ORDER BY TIME
LIMIT 0 , 10

需要帮助每个用户只显示一个数据库结果（PHP）
