[sadeqn]

I need to install Internationalization Functions for php 5.3. ( http://php.net/manual/en/book.intl.php )
I used:
build update
build php n
but that extension did not installed. I checked and saw it is available in ext folder of source but I do not know how can I force it compile and include in my php.ini settings.

It said:

This extension may be installed using the bundled version as of PHP 5.3.0, or as a PECL extension as of PHP 5.2.0. In other words, there are two methods to install the intl extension.

For PHP 5.3 you need to modilfy /usr/local/directadmin/custombuild/custom/suphp/configure.php5 and add line:

--enable-intl

For PHP 5.2.0 you follow instruction on page: http://www.php.net/manual/en/install.pecl.phpize.php
