I got this error after deploying Zend Framework 2 project on my webserver (Ubuntu):

Fatal error: Uncaught exception ‘ZendI18nExceptionExtensionNotLoadedException’ with message ‘ZendI18nTranslator component requires the intl PHP extension’

I had to install PHP Intl extension:

sudo apt-get install php5-intl

Apache Restart:

sudo service apache2 restart

Check what extension compiled:

php -m
