Úvod

Varování

This extension is still in development and it isn't available to public yet.

Požadavky

Instalace

First you should download and install ICU:

Příklad 2201. install ICU on Unix


./configure --disable-threads --enable-extras --enable-icuio --enable-layout
make && make install

Then checkout latest PHP and configure it --with-icu-dir=<dir> option, where <dir> was the dir to where you installed ICU. You don't need to explicitly use this option if you install ICU to a standard location.

If you are really interested in PHP 6 and its Unicode support you should read:

http://www.zend.com/zend/week/php-unicode-design.txt

(and in general http://www.zend.com/zend/week/)

plus cvs/php6/README.UNICODE and cvs/php6/README.UNICODE-UPGRADES



After you compile PHP 6, make sure that you have enabled unicode_semantics = on in php.ini (an old PHP 5 configuration file will not do as it does not provide those new Unicode-related options).
