CLXII. Unicode Functions

Introduction

Unicode Support.

Warning

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

Requirements

ICU 3.4 or later is required.

Installation

First you should download and install ICU:
Example 1. 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.
