php查询IP归属地调用免费接口

php调用免费接口查询IP归属地

淘宝查询接口（较慢）

$url = 'http://ip.taobao.com/service/getIpInfo.php?ip='.$ip;
    //用curl发送接收数据
    $ch = curl_init($url);
    curl_setopt($ch, CURLOPT_ENCODING, 'utf8');
    curl_setopt($ch, CURLOPT_TIMEOUT, 10);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    $location = curl_exec($ch);
    $location = json_decode($location);
    curl_close($ch);
    $ip_location = '';
    if(!empty($location) && $location->code == 0) {
        $ipdata = $location->data;
        //国家
        if ($ipdata->country != "XX") {
            $ip_location = $ip_location . $ipdata->country;
        }
        //地区
        if ($ipdata->region != "XX") {
            $ip_location = $ip_location . $ipdata->region;
        }
        //城市
        if ($ipdata->city != "XX" && $ipdata->city != $ipdata->region) {
            $ip_location = $ip_location . $ipdata->city;
        }
        //县级
        if ($ipdata->county != "XX" && $ipdata->county != $ipdata->city) {
            $ip_location = $ip_location . $ipdata->county;
        }
        //网络
        if ($ipdata->isp != "XX" && $ipdata->isp != $ipdata->city) {
            $ip_location = $ip_location . $ipdata->isp;
        }
    }
    return($ip_location);

126接口

 $ch = curl_init();
    $url = 'http://ip.ws.126.net/ipquery';
    $header = array(
        "CLIENT-IP:$ip",
        "X-FORWARDED-FOR:$ip"
    );
    //用curl发送接收数据
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_HTTPHEADER, $header);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    $location = curl_exec($ch);
    curl_close($ch);
    //转码
    $location = mb_convert_encoding($location, 'utf-8','GB2312');
    //以“”为分界符转换成数组
    $location = explode('"',$location);
    $ip_location = '';
    if ($location && !empty($location[7])){
        $ip_location .= $location[7];
    }
    if ($location && !empty($location[5])){
        $ip_location .= $location[5];
    }
     return $ip_location;

其他接口（这个较上两种更好用）

$ch = curl_init();
     $url = 'https://whois.pconline.com.cn/ipJson.jsp?ip='.$ip;
     //用curl发送接收数据
     curl_setopt($ch, CURLOPT_URL, $url);
     curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
     //请求为https
     curl_setopt ( $ch, CURLOPT_SSL_VERIFYPEER, false );
     curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
     $location = curl_exec($ch);
     curl_close($ch);
     //转码
     $location = mb_convert_encoding($location, 'utf-8','GB2312');
     //var_dump($location);
     //截取{}中的字符串
     $location = substr($location, strlen('({')+strpos($location, '({'),(strlen($location) - strpos($location, '})'))*(-1));
    //将截取的字符串$location中的‘，’替换成‘&’   将字符串中的‘：‘替换成‘=’
     $location = str_replace('"',"",str_replace(":","=",str_replace(",","&",$location)));
     //php内置函数，将处理成类似于url参数的格式的字符串  转换成数组
     parse_str($location,$ip_location);
     return $ip_location['addr'];
