从google反向地理编码api php获取城市名称的最佳方法

<?php
// Google Geocoding API URL
$url = "https://maps.googleapis.com/maps/api/geocode/json?latlng=LAT,LNG&key=YOUR_API_KEY";

// 替换LAT和LNG为实际的经纬度坐标
$lat = 37.7749;
$lng = -122.4194;

// 替换YOUR_API_KEY为你的Google Geocoding API密钥

$url = str_replace("LAT", $lat, $url);
$url = str_replace("LNG", $lng, $url);
$url = str_replace("YOUR_API_KEY", "YOUR_API_KEY", $url);

// 发送HTTP请求
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
curl_close($ch);

// 解析JSON数据
$data = json_decode($response, true);

// 提取城市名称
$city = "";
if ($data['status'] == "OK") {
    foreach ($data['results'][0]['address_components'] as $component) {
        if (in_array("locality", $component['types'])) {
            $city = $component['long_name'];
            break;
        }
    }
}

// 输出城市名称
echo "City: " . $city;
?>
