从数据库中检索数据并将其存储在php中的select标签中

<?php
// 连接数据库
$servername = "数据库主机名";
$username = "数据库用户名";
$password = "数据库密码";
$dbname = "数据库名称";

$conn = new mysqli($servername, $username, $password, $dbname);

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

// 执行查询
$sql = "SELECT id, name FROM your_table";
$result = $conn->query($sql);

// 存储数据
$data = array();
if ($result->num_rows > 0) {
    while ($row = $result->fetch_assoc()) {
        $data[] = $row;
    }
}

// 关闭数据库连接
$conn->close();
?>

<!-- 构建select标签 -->
<select name="your_select">
    <?php foreach ($data as $row): ?>
        <option value="<?php echo $row['id']; ?>"><?php echo $row['name']; ?></option>
    <?php endforeach; ?>
</select>
