Unicode Support.
| Warning |
This extension is still in development and it isn't available to public yet.
|
ICU 3.4 or later is required.
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.
The behaviour of these functions is affected by settings in php.ini.
