I am working on an analytics tool and needed to pull info from the public IPInfoDb. You can get data for 1 – 25 IP’s at a time, and the data is returned as XML or JSON. I wrote a quick Library for PHP that accesses their data using the JSON format. It selects the correct query URL based on how many IP’s you give it.
Installation and Usage
First install the script at some PHP-accessible place, for example, /path/to/class/IPInfo.php. I would also set up autoloading classes to make things simpler. Here’s an example of pulling some information on either an individual IP or several. The class returns an associative array with IP’s for the keys and information arrays (containing city, region, country, latitude, longitude) as the value.
|
1 2 3 4 5 6 7 8 9 10 11 |
// include the class or use autoload instead.
require('/path/to/class/IPInfo.php');
// instantiate the class
$ipinfo = new IPInfo();
// option1
$oneIP = $ipinfo->getInfo('123.234.345.123');
// option2
$multipleIPs = $ipinfo->getInfo( array('123.234.345.123', '1.4.3.123') ); |
