用PHP实现MySQL数据库中多列结果的格式化

<?php
// 连接到MySQL数据库
$servername = "localhost";
$username = "your_username";
$password = "your_password";
$dbname = "your_database";

$conn = new mysqli($servername, $username, $password, $dbname);
if ($conn->connect_error) {
    die("连接失败: " . $conn->connect_error);
}

// 执行查询语句
$sql = "SELECT column1, column2, column3 FROM your_table";
$result = $conn->query($sql);

// 获取查询结果并格式化
if ($result->num_rows > 0) {
    while ($row = $result->fetch_assoc()) {
        $formattedResult = "Column 1: " . $row["column1"] . "<br>";
        $formattedResult .= "Column 2: " . $row["column2"] . "<br>";
        $formattedResult .= "Column 3: " . $row["column3"] . "<br>";
        
        // 输出格式化结果
        echo $formattedResult;
    }
} else {
    echo "没有结果";
}

// 关闭数据库连接
$conn->close();
?>
