Detect ip location, operating system and browser using PHP Detector Library

May 15th, 2007 by Jon Moffet

I've decided to share my PHP Detector library to the public which I've coded somewhere around 2006. The library does wonders in detecting IP address geo-location, operating system and the type of browser used based on its user-agent information.

The ip address->geo-location information is provided for free from ShowIP fakap webservice.

The library is handy for for creating web application which serve content depending on users location and type of operating system/browser that he use or for creating web application that collect web surfers statistical data.

Here's how to use Detector library :

PLAIN TEXT

PHP:

1. require('detector.php');
2. $dip = &new Detector($_SERVER["REMOTE_ADDR"], $_SERVER["HTTP_USER_AGENT"]);
3.  
4. echo "$dip->town";
5. echo "$dip->state, $dip->ccode,$dip->town, ($dip->ipaddress) ";
6. echo "using : $dip->browser $dip->browser_version on $dip->os $dip->os_version";

The live demo of Detector library in action can be viewed here : Detector Library demo.

Requirements

1. Requires PHP 4.4.0 or 5.0.x
2. Requires php cURL extension installed, please refer here for workaround if your server doesn't have PHP cURL extension installed

   Been using this for my web counter for the last month or so; brilliant script thanks. Doesn’t appear to be working today though - your “Detector Library Demo” link isn’t working either. Any idea what the problem is?
   Thanks,
