codeigniter composer integration

Many people so confused about integrate composer with codeigniter, also the documentation is not clear about using it, in the last day I saw a tutorial that used a very bad way to integrate composer with codeigniter 3.0, after this, and by luck I saw a question in stackoverflow with confusing answers that not clearly guide how to use composer with codeigniter, which make me thought to create a tutorial on this subject with step by step example. Not just that, I though to make it very easy by doing a video for my friends to help them doing it faster with real world example, the example about pdfparser library which is a standalone PHP library, provides various tools to extract data from a PDF file . So by the end of this tutorial you will have the freedom to use any package or library that compatible with composer in codeigniter, let is do it.

You can actually use terminal/command prompt inside PhpStorm and using command "composer init" to create composer json file

Greetings! Thanks for your help. I have a question. How will I copy my CI app in cpanel with composer? Simply copy paste the folder from htdocs or need to follow other procedure?
