OOP Fundamentals

In PHP, Object-Oriented Programming (OOP) Fundamentals cover critical aspects like classes, objects, properties, and methods. OOP facilitates efficient code reusability and makes it easier to manage and modify code. For example, here's a code snippet that represents a class with a method and a property in PHP:

class Hello {
    public $greeting = "Hello, world!";

    public function displayGreeting() {
        echo $this->greeting;
    }
}
$hello = new Hello();
$hello->displayGreeting(); // Outputs "Hello, world!"

This snippet defines a class Hello with a property $greeting and a method displayGreeting(). Instances of this class can access these methods and properties. OOP Fundamentals in PHP are much more comprehensive, encompassing concepts like inheritance, encapsulation, and polymorphism.
