If you want to sort Persian Unicode strings (correctly) on the server
side, this is for you. I just tested this on my up2date-d Red Hat 7.1
machine, and it works greatly. This is Linux-only, and the great thing is
again: "You won't need to install anything if you are running the latest
software".
1. Make sure you have PHP >= 4.0.5 and glibc >= 2.2.3.
2. Make sure you have the 'fa_IR' locale installed on your machine. It is
included with glibc. On my machine, it resides at:
/usr/share/i18n/locales/fa_IR
If you are using a distribution other than Red Hat, the file may be
somewhere else, but it's always named 'fa_IR'.
3. Copy the attached samples to a directory where you can run PHP, and
run the PHP script 'sort.php' remotely in a web browser (like
Mozilla 1.1beta or IE 5.0 or later). It reads the file 'sort.txt' and
sorts its entries based on Persian ordering of Arabic letters.
Notes:
* You can see a sample output at:
http://www.bamdad.org/~roozbeh/sort.php
(Make sure you have the latest version of Microsoft fonts if you are
using Microsoft fonts to view Persian pages, otherwise you may see
broken 'Yeh's.)
* Your output may be a little bit different from the one that can be seen
at the above URL, since there is a bug in handling Alef-Hamza vs
Waw-Hamza in the current glibc. This is due to a typo I had made in
the locale file I submitted to glibc in March 2001. I'm cleaning the
locale file and will send the patch to glibc people, to be included in
the next version.
* Behdad and me are working on a mini-Howto for sorting Persian data in
many environments including C, PHP, and PostgreSQL. Keep your fingers
crossed!
* The ordering is based on usage in references like Amid and Mo'in
Persian dictionaries. The test data are by Omid Milani, with some
additions by me.
Good luck,
