Ubuntu 16.04 - Install GPG Extension for PHP 7

Below is a script you can run to install the GPG extension for the PHP 7.0 CLI on Ubuntu 16.04. It may work on other distributions and versions of PHP, but I have not tested that.

Script

#!/bin/bash
sudo apt install libgpgme11-dev php-pear php7.0-dev -y
sudo pecl install gnupg

# Update the php.ini files for Apache and the CLI
SEARCH=";   extension=msql.so"
REPLACE=";   extension=msql.so\nextension=gnupg.so"
FILEPATH="/etc/php/7.0/cli/php.ini"
sudo sed -i "s?$SEARCH?$REPLACE?" $FILEPATH

If you need to add it for php in Apache, then also run:

FILEPATH="/etc/php/7.0/apache2/php.ini"
sudo sed -i "s?$SEARCH?$REPLACE?" $FILEPATH
