On XAMPP (Windows) open the php.ini by opening the control panel, selecting config on apache section and selecting PHP
Then add extension=php_intl and restart Apache
For amazon nginx server (CentOs), try the following:
sudo yum install libicu-devel
sudo yum install php-intl
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.
On Windows, with Apache server, it might not be enough to uncomment the extension in the php.ini file. You also need to copy icu****.dll files (about five of them) from PHP folder to Apache /bin folder.
