Script Title: ipToCountry
Programming Language: PHP
Date Completed: 2013/03/14

Purpose: IPv4 addresses to country code or name. Created as proof of concept, not for main stream use.

Description: Find the country of an IPv4 address.

No database software required, uses a comma-separated values (CSV) file provided by www.webnet77.com.

Very fast table look up engine can look up a list of IP addresses in milliseconds.

Note: Not recommend for use where multiple users require many small instances due to the memory load for loading and unloading the IP database table.

Methods:

$class = new ipToCountry();

$class -> loadFile ( $file_s = ” );

Function to load a CSV file containing the IP database table takes a string value, returns true or false if the file was successfully loaded. Example: ( ‘./IpToCountry.csv’ );

$class -> unloadFile ();

Function to unload the data from the IP database table and clears all results gathered.

$class -> lookUpIp ( $ip_s = ” );

Function to define and look up an IP address, takes a string value.

$class -> getResult ( $option_s = ‘CTRY’ );

Function to get the result of the IP look up. Takes a string value, default ‘CTRY’.

Options are not case sensitize. Returns false if no IP database table has been loaded. Returns unknown if an IP is not listed.

getResult Options:

• REGISTRY

• CTRY
• CNTRY
• COUNTRY

*options are not case sensitize.
