Define global constants with the define function and use all caps to set values that cannot be changed across the PHP script, illustrated by first name, last name, and age.

Learn how to use php global constants to display values with echo, including first name, last name, and age constants, and why reassigning them triggers a syntax error.

Explore how PHP class constructors initialize object attributes when new objects are created, using the __construct method to assign first and last names with $this and the arrow operator.

Explore how PHP object oriented programming uses a two-parameter constructor to assign first and last name attributes with the this keyword, and how objects are created and displayed.

Learn to build unique PHP objects by defining a class constructor, assigning first name, last name, and age with this, creating diverse objects, and displaying them with echo.

Learn to build unique objects in php using a constructor by passing first name, last name, and age, and see the objects display on a local server.

Explore how the destructor runs for each php o o p object, printing attributes like first and last names before the object is destroyed.

Explore access modifiers in PHP, focusing on public visibility for attributes and methods, and learn to instantiate objects, use constructors, this, and arrow accessors to display data.

Explore how the private access modifier restricts visibility to within the same class, declare private properties, and see why external access triggers an error.

Learn how to access and modify private class attributes in PHP using the this keyword and the arrow operator, with constructors and get/set methods to manage values.

Explore constructors and magic methods in PHP object oriented programming fundamentals, learn how constructors initialize data, create unique objects, manage memory with destructors, and enforce private attributes with access modifiers.

Demonstrates a live php oop exercise: instantiate three employee objects with a constructor using user-provided names and IDs, display attributes with methods, and explain magic methods including destructor.

Explore building a PHP object oriented employee system with a private Employee class, constructor, destructor, and get/set methods, creating objects from user data and displaying their info.

Explore PHP object oriented programming by defining and using class constants with the const keyword, accessed via the class name using ::, and understand that their values cannot be changed.

Explore class static attributes in PHP OOP by declaring public static properties on a Person class, accessing them with the class name, and updating values to demonstrate dynamic changes.

Explore PHP object-oriented programming with class static methods, learn how to declare with static, call via the class name using ::, and use static functions without instantiating objects.

Review section 5 recaps class constants, static attributes, and static methods, operating on the class. Assign constants once and access them from the class, while static attributes can be reassigned.

Watch a live demo of a PHP OOP project showcasing static class attributes, class constants, and methods, with default values, value updates, and constants display via the class.

Explore PHP object oriented programming by building a people class with static attributes, a class constant, and static methods to set and display names using self and the double colon.

Explore class inheritance in PHP by creating a person class with private attributes and public getters and setters, then extend it to a child class to reuse code via extends.

Explore how a parent class provides attributes and methods, and how a child class inherits them in php, using set and get methods for first name and last name.

Explore how the public access modifier interacts with inheritance in PHP OOP, demonstrating why encapsulation requires private attributes and how public data can be exploited.

Examine how the private access modifier affects inheritance in PHP OOP, showing that private attributes and methods are not inherited or accessible by child classes.
