在wamp上用php从mysql数据库中随机选择

$servername = "localhost";
$username = "root";
$password = "";
$dbname = "your_database_name";

// 创建连接
$conn = new mysqli($servername, $username, $password, $dbname);

// 检查连接是否成功
if ($conn->connect_error) {
    die("连接失败: " . $conn->connect_error);
}

$sql = "SELECT * FROM your_table_name ORDER BY RAND() LIMIT 1";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
    // 输出数据
    while($row = $result->fetch_assoc()) {
        echo "随机选择的数据: " . $row["column_name"];
    }
} else {
    echo "没有找到数据";
}

$conn->close();
