Introduction
|
|
------------
|
|
|
|
The class idna_convert allows to convert internationalized domain names
|
|
(see RFC 3490, 3491, 3492 and 3454 for detials) as they can be used with various
|
|
registries worldwide to be translated between their original (localized) form
|
|
and their encoded form as it will be used in the DNS (Domain Name System).
|
|
|
|
The class provides two public methods, encode() and decode(), which do exactly
|
|
what you would expect them to do. You are allowed to use complete domain names,
|
|
simple strings and complete email addresses as well. That means, that you might
|
|
use any of the following notations:
|
|
|
|
- www.nörgler.com
|
|
- xn--nrgler-wxa
|
|
- xn--brse-5qa.xn--knrz-1ra.info
|
|
|
|
Errors, incorrectly encoded or invalid strings will lead to either a FALSE
|
|
response (when in strict mode) or to only partially converted strings.
|
|
You can query the occured error by calling the method get_last_error().
|
|
|
|
Unicode strings are expected to be either UTF-8 strings, UCS-4 strings or UCS-4
|
|
arrays. The default format is UTF-8. For setting different encodings, you can
|
|
call the method setParams() - please see the inline documentation for details.
|
|
ACE strings (the Punycode form) are always 7bit ASCII strings.
|
|
|
|
ATTENTION: We no longer supply the PHP5 version of the class. It is not
|
|
necessary for achieving a successfull conversion, since the supplied PHP code is
|
|
compatible with both PHP4 and PHP5. We expect to see no compatibility issues
|
|
with the upcoming PHP6, too.

|
idna_convert.class.php - The actual class
|
|
idna_convert.create.npdata.php - Useful for (re)creating the NPData file
|
|
npdata.ser - Serialized data for NamePrep
|
|
example.php - An example web page for converting
|
|
ReadMe.txt - This file
|
|
LICENCE - The LGPL licence file
|
|
|
|
The class is contained in idna_convert.class.php.
|
|
MAKE SURE to copy the npdata.ser file into the same folder as the class file
|
|
itself!

Examples
|
|
--------
|
|
|
|
1. Say we wish to encode the domain name nörgler.com:
|
|
|
|
// Include the class
|
|
include_once('idna_convert.class.php');
|
|
// Instantiate it *
|
|
$IDN = new idna_convert();
|
|
// The input string, if input is not UTF-8 or UCS-4, it must be converted before
|
|
$input = utf8_encode('nörgler.com');
|
|
// Encode it to its punycode presentation
|
|
$output = $IDN->encode($input);
|
|
// Output, what we got now
|
|
echo $output; // This will read: xn--nrgler-wxa.com
|
|
|
|
|
|
2. We received an email from a punycoded domain and are willing to learn, how
|
|
the domain name reads originally
|
|
|
|
// Include the class
|
|
include_once('idna_convert.class.php');
|
|
// Instantiate it (depending on the version you are using) with
|
|
$IDN = new idna_convert();
|
|
// The input string
|
|
$input = 'andre@xn--brse-5qa.xn--knrz-1ra.info';
|
|
// Encode it to its punycode presentation
|
|
$output = $IDN->decode($input);
|
|
// Output, what we got now, if output should be in a format different to UTF-8
|
|
// or UCS-4, you will have to convert it before outputting it
|
|
echo utf8_decode($output); // This will read: andre@börse.knörz.info
|
|
|
|
|
|
3. The input is read from a UCS-4 coded file and encoded line by line. By
|
|
appending the optional second parameter we tell enode() about the input
|
|
format to be used
|
|
|
|
// Include the class
|
|
include_once('idna_convert.class.php');
|
|
// Instantiate it
|
|
$IDN = new dinca_convert();
|
|
// Iterate through the input file line by line
|
|
foreach (file('ucs4-domains.txt') as $line) {
|
|
echo $IDN->encode(trim($line), 'ucs4_string');
|
|
echo "\n";
|
|
}
|
|
|
|
|
|
NPData
|
|
------
|
|
|
|
Should you need to recreate the npdata.ser file, which holds all necessary translation
|
|
tables in a serialized format, you can run the file idna_convert.create.npdata.php, which
|
|
creates the file for you and stores it in the same folder, where it is placed.
|
|
Should you need to do changes to the tables you can do so, but beware of the consequences.
