通过GeoIP获取ip所属地 (国家，城市，时区，邮编，经纬度等)

来源： http://www.phpandstuff.com/articles/geoip-country-lookup-with-php

 

GeoIP + PHP

$country_code 
";
 
    // 获取国家名称
    $country_name = geoip_country_name_by_addr($gi, $_SERVER['REMOTE_ADDR']);
    echo "Your country name is: $country_name 
";
 
    // close the database
    geoip_close($gi);
 
    //运行结束时间
    $endTimes = utime();
    $runTimes = sprintf( '%0.4f', ( $endTimes - $startTimes ) );
    echo "Processed in " . $runTimes . "second.";
?>

 

注：在本地测试的话因 为$_SERVER['REMOTE_ADDR']和$_SERVER['REMOTE_ADDR']可能是127.0.0.1，所 以输出的内容为空。可以自己带入IP测试

 

或者 使用某网站的API

 

API 1.

 

1. 返回文字

 

http://api.hostip.info/get_html.php?ip=12.215.42.19&position=true

 

2. 返回图片

 

 

 

API 2. （需要申请api key ，免费的，类似google）

 

城市：

 

http://api.ipinfodb.com/v3/ip-city/?key=&ip=74.125.45.100

 

国家（更快） ：

 

http://api.ipinfodb.com/v3/ip-country/?key=&ip=74.125.45.100

 

 

Parameter	Required	Default	Value
key	Yes		API key provided with your free account.
ip	No	Client IP	IP address
format	No	raw	raw, xml, json
callback	No		Required when using json callback.

Please use the appropriate API for your needs. You can help us keep the load low on our servers by making sure that :

• If you only need the country name, avoid using the city precision API.
• If you track your visitors, avoid querying our API for all your page views (you can store the geolocation in a cookie, see below for an example)

API	Precision	Timezone	Domains lookups
ip-city	City	Yes	Yes
ip-country	Country	No	Yes

使用类：

 

apiKey = $key;
	}

	public function getError(){
		return implode("\n", $this->errors);
	}

	public function getCountry($host){
		return $this->getResult($host, 'ip-country');
	}

	public function getCity($host){
		return $this->getResult($host, 'ip-city');
	}

	private function getResult($host, $name){
		$ip = @gethostbyname($host);

		if(preg_match('/^(?:25[0-5]|2[0-4]\d|1\d\d|[1-9]\d|\d)(?:[.](?:25[0-5]|2[0-4]\d|1\d\d|[1-9]\d|\d)){3}$/', $ip)){
			$xml = @file_get_contents('http://' . $this->service . '/' . $this->version . '/' . $name . '/?key=' . $this->apiKey . '&ip=' . $ip . '&format=xml');

			try{
				$response = @new SimpleXMLElement($xml);

				foreach($response as $field=>$value){
					$result[(string)$field] = (string)$value;
				}

				return $result;
			}
			catch(Exception $e){
				$this->errors[] = $e->getMessage();
				return;
			}
		}

		$this->errors[] = '"' . $host . '" is not a valid IP address or hostname.';
		return;
	}
}
?>

 

setKey('');
 
//Get errors and locations
$locations = $ipLite->getCity($_SERVER['REMOTE_ADDR']);
$errors = $ipLite->getError();
 
//Getting the result
echo "
\n";
echo "First result
\n";
if (!empty($locations) && is_array($locations)) {
  foreach ($locations as $field => $val) {
    echo $field . ' : ' . $val . "
\n";
  }
}
echo "
\n";
 
//Show errors
echo "
\n";
echo "Dump of all errors
\n";
if (!empty($errors) && is_array($errors)) {
  foreach ($errors as $error) {
    echo var_dump($error) . "

\n";
  }
} else {
  echo "No errors" . "
\n";
}
echo "
\n";
