Contact CLI Development

OpenClassrooms project context :
As part of an exercise focused on object-oriented programming, I developed a PHP application that runs in the command line. The goal was to work with PHP in a non-web environment, allowing me to focus on business logic, object-oriented architecture, and code organization without the constraints of a graphical interface.

The project involved designing a simple yet robust tool capable of managing an address book directly from the terminal. Users needed to interact with the program through text-based commands, while the code had to be structured according to object-oriented programming principles. I also chose to go beyond the initial scope by adding extra usability and scalability features.

I designed an object-oriented PHP contact manager driven by commands entered in the terminal.

More specifically, I:

• structured the application around classes dedicated to contact management;
• implemented the main commands:
• • list to display the contact list,
  • detail to view a contact record,
  • create to add a contact,
  • delete to remove a contact,
  • quit to exit the program;
• added a help command to display the available commands and their descriptions;
• developed a modify command to update an existing contact’s information;
• improved object display by replacing the standard method with the __toString() magic method;
• handled user command syntax within the console interface;
• organized the project with Git and GitHub for code tracking.

The application makes it possible to manage an address book smoothly directly from the terminal, with a complete command set and a more advanced object-oriented structure. This project helped me strengthen my PHP OOP skills, better understand CLI tool design, and integrate technical refinements that improve code maintainability.
