php - 在网站上显示 MySQL SHOW 表的结果

Question

我正在尝试在我的网站上显示数据库中的表列表，但找不到在实际页面上显示 SHOW table 输出的方法。这是我的代码:

<?php
$servername = "localhost";
$username = "***";
$password = "***";
$dbname = "***";

//Create Connection

$conn = mysqli_connect($servername, $username, $password, $dbname);

//Check Connection

if (!$conn) {
        die("Connection failed: " .mysqli_connect_error());
}

$sql = "SHOW tables";

$result = mysqli_query($conn, $sql);

while ($row = mysqli_num_rows($result)) {
        echo $row[];
        }

mysqli_close($conn);

?>

Answer 1

应该是，

while($table = mysqli_fetch_array($result)) { 
    echo($table[0] . "<BR>");  
}
