PHP 5.3 seems to be missing Intl extension by default

php linux ubuntu icu intl

My system is Ubuntu 12.04, PHP 5.3, and I'm trying to run some basic Intl code like this:

<?php
$coll  = collator_create('en_US');
$result = collator_compare($coll, "string#1", "string#2");

and it outputs

PHP Fatal error:  Call to undefined function collator_create()

Wasn't Intl extension supposed to be bundled with PHP since version 5.3?

PHP was installed via apt-get with this command line (I don't use Apache):

apt-get install php5 php5-cli php5-mysql php5-cgi php5-fpm php5-curl php-apc php5-memcache php5-memcached php5-common php5-gd php-xml-parser php-pear php5-imap php5-mcrypt php5-xdebug php5-suhosin

And here is what php -v produces:

PHP 5.3.10-1ubuntu3.5 with Suhosin-Patch (cli) (built: Jan 18 2013 23:40:19)

You have specify --enable-intl when installing to use the bundled version of intl, or you can install it via PECL. See: http://www.php.net/manual/en/intl.installation.php

apt-get install php5-intl will also work.
