PHP根据IP地址获取地理位置城市和经纬度信息

/** 根据IP地址 获取地理位置*/
function getLocationByIP($ip) {
    $url = "http://ip-api.com/json/{$ip}?lang=zh-CN&fields=status,message,country,countryCode,region,regionName,city,lat,lon,timezone,isp,org,as";
    $response = file_get_contents($url);
    $data = json_decode($response, true);

    if ($data['status'] == 'success') {
    	return $data;
        
    } else {
        return ''; // 或者返回错误信息
    }
}

在浏览器里请求这个地址

http://ip-api.com/json/124.236.132.47?fields=status,message,country,countryCode,region,regionName,city,lat,lon,timezone,isp,org,as&lang=zh-CN
