如何将php搜索结果输出到html表？

<?php
// 连接到数据库并执行查询
$conn = new mysqli("数据库主机", "用户名", "密码", "数据库名");
if ($conn->connect_error) {
    die("数据库连接失败: " . $conn->connect_error);
}

$searchKeyword = $_GET['keyword']; // 获取用户输入的搜索关键字

$sql = "SELECT * FROM 表名 WHERE 字段 LIKE '%$searchKeyword%'";
$result = $conn->query($sql);

// 将搜索结果输出为HTML表格
if ($result->num_rows > 0) {
    echo "<table>";
    echo "<tr><th>字段1</th><th>字段2</th><th>字段3</th></tr>";
    while ($row = $result->fetch_assoc()) {
        echo "<tr>";
        echo "<td>" . $row['字段1'] . "</td>";
        echo "<td>" . $row['字段2'] . "</td>";
        echo "<td>" . $row['字段3'] . "</td>";
        echo "</tr>";
    }
    echo "</table>";
} else {
    echo "没有找到匹配的结果。";
}

$conn->close();
?>
