How do I install ioncube loader on EasyEngine v4

I’m new in this easyengine community and I’m a complete amateur. I was trying to install the ioncube loader php extension but couldn’t. Can anyone help me out?
I followed this tutorial:
But after I copying the ioncube loader in the site container and again logged in in the site container i ran the command “php -i | grep enxtension_dir” and it didn’t show the extension directory.
I’m stuck.
