如何利用php语法查询ip归属地

javascript可以查询ip归属地，那么php可以实现吗？下面web建站小编给大家详细介绍一下！

1、开通接口

ip地址归属地接口服务使用的聚合数据提供的免费接口，可以通过https://www.juhe.cn/docs/api/id/1?s=ipkdcn注册及开通。

2、根据查询的IP地址，查询该IP所属的区域

$appkey = "*********************";

//根据查询的IP地址，查询该IP所属的区域
$url = "http://apis.juhe.cn/ip/ipNew";
$params = [
    "ip" => "192.168.0.1",
    "key" => $appkey,
];
$paramstring = http_build_query($params);
$content = juheHttpRequest($url, $paramstring, 1);
$result = json_decode($content, true);
if ($result) {
  if ($result['error_code'] == 0) {
    echo "国家：{$result['result']['Country']}" . PHP_EOL;
    echo "省份：{$result['result']['Province']}" . PHP_EOL;
    echo "城市：{$result['result']['City']}" . PHP_EOL;
    echo "运营商：{$result['result']['Isp']}" . PHP_EOL;
  } else {
    echo "{$result['error_code']}:{$result['reason']}" . PHP_EOL;
  }
} else {
    echo "请求失败";
}

3、请求接口返回内容

/**
 * 请求接口返回参数介绍
 * @param string $url [请求的URL地址]
 * @param string $params [请求的参数]
 * @param int $ipost [是否采用POST形式]
 * @return  string
 */
function juheHttpRequest($url, $params = false, $ispost = 0)
{
  $httpInfo = array();
  $ch = curl_init();
  
  curl_setopt($ch, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_1);
  curl_setopt($ch, CURLOPT_USERAGENT, 'JuheData');
  curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 3);
  curl_setopt($ch, CURLOPT_TIMEOUT, 5);
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
  curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
  if ($ispost) {
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $params);
    curl_setopt($ch, CURLOPT_URL, $url);
  } else {
    if ($params) {
      curl_setopt($ch, CURLOPT_URL, $url . '?' . $params);
    } else {
      curl_setopt($ch, CURLOPT_URL, $url);
    }
  }
  $response = curl_exec($ch);
  if ($response === FALSE) {
    //echo "cURL Error: " . curl_error($ch);
    return false;
  }
  $httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
  $httpInfo = array_merge($httpInfo, curl_getinfo($ch));
  curl_close($ch);
  return $response;
}
