Hello im new

Hello i tired to understand some php frameworks like codeigniter and laravel when i see their code differences, CI is a bit outdated and laravel is updated hence does this affect security?

 

first thing i found on CI is every file in app or system have some thing like this.

<?php if (!defined('CONSTANT_ROOT')) { exit('Message here'); }

Does this really protect the files?
