使用php将mysql DB中的地址读取到数组中进行地理编码

<?php
// 连接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);
}

// 查询地址数据
$sql = "SELECT address FROM your_table";
$result = $conn->query($sql);

// 遍历结果集
$addresses = array();
if ($result->num_rows > 0) {
    while ($row = $result->fetch_assoc()) {
        // 读取地址字段
        $address = $row["address"];

        // 地理编码
        // 这里使用腾讯地图API作为示例，你可以根据实际情况选择其他地理编码的API
        $apiUrl = "https://apis.map.qq.com/ws/geocoder/v1/?address=" . urlencode($address) . "&key=your_api_key";
        $response = file_get_contents($apiUrl);
        $data = json_decode($response, true);

        if ($data["status"] == 0) {
            // 构建数组
            $coordinates = $data["result"]["location"];
            $addresses[$address] = $coordinates;
        }
    }
}

// 关闭数据库连接
$conn->close();

// 打印结果
print_r($addresses);
?>
