Over time, PHP and its various tools have become more advanced and easier to use. This progression has enabled individuals to develop their own frameworks, utilizing the core PHP language itself. While there exist numerous reputable, well-known, secure, updated, and well-documented open-source PHP frameworks, they can be conveniently installed and utilized through Git or Composer commands.

However, for those who are new to PHP and wish to gain a deeper understanding of how elements like function classes, namespace objects, and others interact within a framework, there is no substitute for hands-on learning. Therefore, let us commence by constructing a straightforward framework from the ground up. It is important to note that we are not creating anything novel; instead, we will simply employ various features and functions inherent to PHP.

Please bear in mind that this framework is intended solely for educational purposes and should not be employed for professional use or on a production server. This tutorial is not suitable for novices in PHP; a basic understanding of object-oriented programming concepts is required. It is also advisable to have a solid grasp of MVC and SOLID Design Patterns. Additionally, it is highly recommended to gain a clear understanding of both Git and Composer.
