How to install PHP intl extension in Ubuntu 14.04

Question

I have a hard time to find exact method to install PHP intl extension in Ubuntu 14.04.

I tried with sudo apt-get install php5-intl but

Answer 1

For php5 on Ubuntu 14.04

sudo apt-get install php5-intl

For php7 on Ubuntu 16.04

sudo apt-get install php7.0-intl

For php7.2 on Ubuntu 18.04

sudo apt-get install php7.2-intl

Anyway restart your apache after

sudo service apache2 restart

IMPORTANT NOTE: Keep in mind that your php in your terminal/command line has NOTHING todo with the php used by the apache webserver!

If the extension is already installed you should try to enable it. Either in the php.ini file or from command line.

Syntax:

php:

phpenmod [mod name]

apache:

a2enmod [mod name]
