Complete PHP OOP Concepts for Absolute Beginners + Projects

🚀 Course Outline for Advanced PHP Programming

The advanced PHP programming course is designed to take your skills to the next level. Here's a comprehensive outline of what you'll learn, including real-time examples and practical applications:

1. PHP Core Concepts Recap:

   • Basic syntax review
   • Data types and variables
   • Control structures (if, switch, for, foreach, while, do-while)
   • Functions (defining, calling, variadic functions)
   • Error handling with try/catch blocks

2. Advanced Data Types:

   • Arrays (associative, multidimensional) and array functions
   • Objects and classes
   • Resource types (files, database connections, etc.)

3. Object-Oriented Programming (OOP):

   1. What is OOP?
      • Conceptual understanding of OOP principles
   2. Inheritance:
      • Understanding "is-a" relationship
      • Child classes inheriting from parent classes
      • Accessing methods and properties in child classes
   3. Methods and Properties Access Modifiers:
      • Private, protected, and public access levels
   4. Overriding Methods:
      • Child class overriding parent class methods
   5. Inheritance Types:
      • Single vs. multiple inheritance (PHP supports single inheritance)
   6. Real-time example with Course and Lecture classes
   7. Final Keyword Usage:
      • Preventing method and property overrides in child classes

4. Interfaces and Abstract Classes:

   1. What is an Interface?
      • Declaring and implementing interfaces
   2. Multiple interface implementation
   3. Use cases for interfaces
   4. Creating a Phone interface and its implementation
   5. Abstract Classes:
      • Declaring abstract classes and methods
      • Using abstract classes in real-world scenarios

5. Static Properties and Methods:

   1. Understanding static context
   2. Defining and accessing static members
   3. Use cases for static properties and methods
   4. Real-time example with class utilities

6. Polymorphism:

   1. Understanding the concept of polymorphism
   2. Real-world examples (e.g., database abstraction layers)

7. Encapsulation and Abstraction:

   1. Data encapsulation concepts
   2. Practical example with a class that encapsulates user data
   3. Data abstraction concepts
   4. Practical example with a class that abstracts file operations

8. Overriding vs. Overloading:

   1. Understanding the differences between overriding and overloading
   2. Examples and practical use cases

9. Magic Methods:

   1. Understanding magic methods (e.g., _set, _get, _call, _toString, _debuginfo)
   2. Practical examples of magic methods in action

10. Type Hinting:

11. What is type hinting?

12. Examples with arrays and objects

13. Writing a Posts class with proper type hinting for saving and fetching posts

14. Namespaces:

15. Understanding namespaces and their usage

16. Defining and using namespaces

17. Alias names and global namespace considerations

18. Dependency Injection:

19. What is dependency injection?

20. Practical example with a University class and Student objects

21. Object Manipulation:

22. Cloning objects, serializing objects, caching objects, comparing objects, and iterating over objects

23. Traits:

24. What are traits?

25. Defining and using traits

26. Implementing a trait for file operations and integrating it with the Posts class

27. Autoloading:

28. Understanding autoloading mechanisms

29. Examples of autoloading functions and spl

30. SOLID Principles:

    • Single Responsibility Principle (SRRP)
    • Open Closed Principle (SPOOC)
    • Liskov Substitution Principle (LSP)
    • Interface Principle (IIRP)
    • Dependency Principle (DDPP)

31. Projects:

32. Database class for database operations

33. Students class with enrollment and management features

34. University application class that integrates the Course, Lecture, and Student classes � Note to Learners: This course outline is indicative and may be adjusted to fit the scope of learning outcomes as defined by the relevant education and training standards.
