PHP Classes and Objects
PHP classes define objects with properties and visibility modifiers.
Introduction to PHP Classes
In PHP, a class is a blueprint for creating objects. It defines properties and methods that the created objects will have. Classes can help organize and group related functionalities together, making code more modular and reusable.
Defining a PHP Class
A basic PHP class contains properties (variables) and methods (functions). Properties can hold data specific to each object, while methods define behaviors that the object can perform.
Properties and Visibility Modifiers
Properties in a class can have visibility modifiers: public, protected, and private. These modifiers determine how properties can be accessed.
- Public: The property can be accessed from anywhere.
- Protected: The property can be accessed within the class and by classes derived from that class.
- Private: The property can only be accessed within the class itself.
Creating Objects from Classes
Once a class is defined, you can create objects from it. Each object is an instance of the class, and it can have its own properties and behaviors as defined by the class.
