How can one separate the basic system from the project in PHP development?

One way to separate the basic system from the project in PHP development is to use a modular approach. This involves organizing your code into separate modules or components that can be easily reused in different projects. By creating a basic system that contains common functionalities and then building specific project features on top of it, you can ensure better code organization, reusability, and maintainability.

// Basic System Module
class BasicSystem {
    public function commonFunctionality() {
        // Common functionality code here
    }
}

// Project Module
class Project extends BasicSystem {
    public function specificFunctionality() {
        // Specific functionality code here
    }
}

// Implementation
$project = new Project();
$project->commonFunctionality();
$project->specificFunctionality();
