Save Location to DB based on IP address

Question

I am trying to use hostip in order to save to DB user's general area/ location, according to IP address. However I am not sure how to parse the data from the output I am receiving.

    <?php
        $ip = $_SERVER['REMOTE_ADDR'];
        $data = json_decode(file_get_contents("http://api.hostip.info/get_html.php?ip=$ip")); //<-not sure how
        $country = $data['Country'];
        $city = $data['City']; 
    ?>

You can see here how I am receiving the data: http://api.hostip.info/get_html.php?ip=00.0.00.00

Another option was to use the first answer here (using ipinfodb): Getting location details from IP in PHP , but it doesn't even display any data, even when I try inserting my IP in the url, let alone parse the results, so I changed to the above.

Answer 1

So, according to ipinfodb , you will have to sign up for an API key. But they have an API class , which's getCountry($host) will get the country of the IP after you gave the protected $apiKey = ''; your API key. Or if you don't want to use that, you can use their XML or their JSON API.

UPDATE 1

Or, if that is too hard for you, then use explode on the newline separator (\\n) at the other service. Or, perhaps use another service.

UPDATE 2

Seems that geoPlugin , mentioned in the question you linked does not require an API key. Their code to use is echo var_export(unserialize(file_get_contents('http://www.geoplugin.net/php.gp?ip='.$ip))); .

Answer 2

Simply using $data['country'] will not work because the given result is not an object or array. You need to split the content into an array or, even better, retrieve it as a JSON object and then use:

$data = json_decode($data);

To give you the data in an array.

Despite the above, I wouldn't advise getting locations from IP Addresses because it is incredibly inaccurate! It returns the location of the Host server, not necessarily the location of the user.

EDIT:

Use the JSON API: http://ipinfodb.com/ip_location_api_json.php

Update:

Steps to implementing the JSON API:

1. Register for an API key here: http://ipinfodb.com/register.php . This will allow you to retrieve results from their server, without this it will not work.
2. You do not need to implement any SDK to get this to work, so all you should need is this:

Copy and past the following PHP code:

// Set the parameters
$ip_address = $_SERVER['REMOTE_ADDR'];
$api_key = 'YOUR_API_KEY_HERE';

// Get the data
$data = file_get_contents("http://api.ipinfodb.com/v3/ip-city/?key=$api_key&ip=$ip_address&format=json");

// Decode the JSON result into an array
$data = json_decode($data);

// All data can now be accessed using the associative array $data
$country = $data['Country']; // Country
$city = $data['City']; // City

Answer 3

您可以使用换行分隔符将其拆分为一个数组，然后使用一系列字符串操纵符对其进行清理...或者您可以找到一个将数据返回为json的服务，这将完全缓解所有这些麻烦。

Answer 4

you can make an array like this :

array(
   array(
        'ip' => '0.0.0.0',
        'country' => 'someplace',
        'city' => 'somecity'm ,
        'data' => 'somedata'),
     array(
        'ip' => '0.0.0.0',
        'country' => 'someplace',
        'city' => 'somecity'm ,
        'data' => 'somedata'),
.
.
. );

and then serialize the array and save it via ip address in database and then you just have 2 table column :

ip ::: info 

then you can use a function to retrieve data from db and universalize the array retrieved from info column.more information about php serialze
