Study Notes
OOP Concepts
- OOP is a programming paradigm that relates to the real world by considering everything as an object, which holds its own properties (data) and behaviors (functions).
Classes and Objects
- A class is a blueprint or template used to hold objects along with their behavior and properties.
- An object is an instance or occurrence of a class.
- Example: A Car class can have properties like make, color, year, speed limit, etc., and each object (Audi, Mercedes, BMW, etc.) created from the class inherits all the properties and behaviors, but with different values.
Defining a PHP Class
- A class is defined in PHP using the
class
keyword, followed by the name of the class and a pair of curly braces ({}
).
OOP Concepts
- OOP relates programming to the real world by considering everything as an object, which holds its own properties (data) and behaviors (functions) via methods.
Classes & Objects
- A class is a blueprint or template that holds objects along with their behavior and properties.
- An object is an instance or occurrence of a class.
- Example: A class named Car can have properties like make, color, year, speed limit, etc.
- Variables like make,make, make,color, year,andyear, and year,andspeed can hold the values of these properties.
- When individual objects (e.g., Audi, Mercedes, BMW) are created from the Car class, they inherit all the properties and behaviors from the class, but each object will have different values for the properties.
Defining a PHP Class
- A class is defined using the
class
keyword, followed by the name of the class and a pair of curly braces ({}
). - This definition creates a blueprint or template for objects to be created from.
