在PHP中自动定位用户的地理位置

<?php
$ip = $_SERVER['REMOTE_ADDR'];
$apiUrl = 'https://apis.map.qq.com/ws/location/v1/ip';

$params = [
    'ip' => $ip,
    'key' => 'YOUR_TENCENT_MAP_API_KEY',
];

// 使用cURL发送HTTP请求
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $apiUrl . '?' . http_build_query($params));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
curl_close($ch);

$data = json_decode($response, true);

if ($data['status'] === 0) {
    $result = $data['result'];
    $nation = $result['ad_info']['nation'];       // 国家
    $province = $result['ad_info']['province'];   // 省份
    $city = $result['ad_info']['city'];           // 城市

    echo "您所在的地理位置是：$nation $province $city";
} else {
    echo "定位失败";
}
?>
