Next, find the PHP extensions directory on the system by running the commands below
php -i | grep extension_dir
extension_dir => /usr/lib/php/20170718 => /usr/lib/php/20170718
You should see the directory PHP uses for its extensions.
Next, copy the ionCube loader into the PHP directory above, by running the commands below. do this for each loader for the particular PHP version.
sudo cp /tmp/ioncube/ioncube_loader_lin_7.1.so /usr/lib/php/20170718/ sudo cp /tmp/ioncube/ioncube_loader_lin_7.2.so /usr/lib/php/20170718/
When you’re done. open the default PHP config file and include the loader.

PHP with CLI
sudo nano /etc/php/7.2/cli/php.ini
PHP with CGI
sudo nano /etc/php/7.2/cgi/php.ini
Then add a line in the file to include ionCube loader. it can be anywhere in the file below [PHP] line. however, you’ll need to specify the exact location of the loader you copied above.
zend_extension = /usr/lib/php/20170718/ioncube_loader_lin_7.2.so
Save the file and restart PHP and / or the webserver.
