How to check the IP address ownership? The following article will introduce to you how to use PHP to query the location of the IP address.

Steps for PHP to query the IP address:

1. Open the interface

P The free interface provided by the aggregated data used by the address attribution interface service can be registered and activated through https://www.juhe.cn/docs/api/id/1?s=cpphpcn.

2. Based on the queried IP address, query the area to which the IP belongs.

// 接口请求Key，可以通过https://www.juhe.cn/docs/api/id/1免费申请开通
$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" => "112.112.11.11",//需要查询的IP地址或域名
    "key" => $appkey,//应用APPKEY(应用详细页查询)
];
$paramstring = http_build_query($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. Request the content returned by the interface

/**
 * 请求接口返回内容
 * @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;
}
