;extension=php_intl.dll

extension=php_intl.dll

php internationalization wamp

if you see this on Debian / other Linux platforms.

sudo apt-get install php5-intl - for PHP 5.6

sudo apt-get install php7.0-intl - PHP 7+

sudo yum install php70-intl

After that restart Apache services.

sudo service apache2 restart restart apache to get the changes.
