Installation

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.

Information zur Installation dieser PECL-Extension finden sie im Kapitel Installation von PECL-Extensions. Zus√§tzliche Informationen wie neue Releases, Downloads, Quelldateien, Maintainerinformation und ein CHANGELOG finden Sie hier: » http://pecl.php.net/package/intl.

Alternatively, --enable-intl will enable the bundled version while compiling PHP.

If your ICU is installed to a non-standard directory then you might want to specify its location in LD_LIBRARY_PATH environment variable so that dynamic linker can find it:

$ export LD_LIBRARY_PATH=/opt/icu/lib

Otherwise, if PHP and ICU are installed to their default locations, then the additional options to `configure' are not needed.

On windows servers, open your php.ini (which should be in Program Files/PHP), and simply uncomment the extension.
extension=php_intl.dll
Restart IIS Webserver - done.

You need to install the library.

yum install libicu-devel

Will get it working with "pecl install intl"

I'm running on Mac OS X using a MacPorts install. According to this page, my vanilla version of PHP 5.3.5 from MacPorts should include the intl functions by default. As far as I can see from phpinfo(), the MacPorts version did not disable it. However, the functions aren't visible and don't work.

It seems to require an additional:

sudo port install php5-intl

After which everything bursts into life.

To install on windows uncommenting the dll in php.ini is not enough you also need to include several other libraries in your system path (not user path). Found these details here: http://stackoverflow.com/a/6086991/819883

OS : CentOS 5.10
PHP : 5.5.12
We tried installing via *pecl install intl* , but we were getting below warning in php error logs

PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/local/lib/php/extensions/no-debug-non-zts-20121212/intl.so' - /usr/lib64/libstdc++.so.6: version `GLIBCXX_3.4.9' not found (required by /usr/local/lib/libicuio.so.55) in Unknown on line 0

Later we tried icu source from http://site.icu-project.org/download
Compile ICU ./configure --prefix=/opt/icu && make && make install

And post which we compiled PHP via source with following configurations:
  --enable-intl
  --with-icu-dir=/opt/icu

On Fedora 18 "pecl install intl" wasn't working after "yum -y install icu" so I had to run "yum -y install php-intl" instead
