You can do it in php.ini where you can specify and comment below extension
;extension=intl or ;extension=php_intl.dll [ remove ";" semicolon and all done ] or simply add below all extensions ]
extension=intl or extension=php_intl.dll
if you are using any php development environment like XAMPP or WAMP on windows machine check the settings and enable php extension for apache server.
if you are using ubuntu you can simply type the command below and restart apache or whatever server you have
sudo apt-get update
sudo apt-get install php7.0-intl [ if your php 7 ]
or
sudo apt-get install php5.6-intl [ in case still you are using php 5.6 ]
restart the server once done.
