PHP GeoIPLocation Library

PHP GeoIPLocation Library by Chirag Mehta is a single PHP file that will let you determine the country of location for any given IP address.

GeoIPLoc does not require any large database tables, flat text files, or any special configuration on your server. Using GeoIPLoc is as easy as calling the getCountryFromIP() function with any IP address of the form 'x.x.x.x' where 'x' is any integer between 0 and 255.

The library is automatically updated once a day by downloading the free IP address database from Software77.net. The auto-generation utility then sorts and compacts the data in the most efficient way to reduce the size of the resulting PHP file.

Additionally, the library uses a rudimentary caching algorithm that drastically speeds up batch querying of IP addresses, e.g. while parsing browser access logs.

Usage

1. Download PHP GeoIPLocation Library from the link above.
2. Extract geoiploc.php to any folder on your server that is accessible by a web browser.
3. Include the "geoiploc.php file and call getCountryFromIP() function with any IP address.
4. View the sample code below for more details.

Sample Code

<?php

  include("geoiploc.php"); // Must include this

  // ip must be of the form "192.168.1.100"
  // you may load this from a database
  $ip = $_SERVER["REMOTE_ADDR"];
  echo "Your IP Address is: " . $ip . "<br />";

  echo "Your Country is: ";
  // returns country code by default
  echo getCountryFromIP($ip);
  echo "<br />\n";

  // optionally, you can specify the return type
  // type can be "code" (default), "abbr", "name"

  echo "Your Country Code is: ";
  echo getCountryFromIP($ip, "code");
  echo "<br />\n";

  // print country abbreviation - case insensitive
  echo "Your Country Abbreviation is: ";
  echo getCountryFromIP($ip, "AbBr");
  echo "<br />\n";

  // full name of country - spaces are trimmed
  echo "Your Country Name is: ";
  echo getCountryFromIP($ip, " NamE ");
  echo "<br />\n";?>

//get the city name inside the node <gml:name> and </gml:name>
