Object-Oriented PHP

Modern PHP development heavily relies on Object-Oriented Programming (OOP) principles.

Classes and Objects

<?php
class User {
    public $name;
    private $email;

    public function __construct($name, $email) {
        $this->name = $name;
        $this->email = $email;
    }

    public function getEmail() {
        return $this->email;
    }
}

$user = new User("John Doe", "john@example.com");
echo $user->name; // John Doe
?>

Key Concepts

• Encapsulation: Using public, private, and protected visibility
• Inheritance: Extending classes
• Polymorphism: Method overriding
• Traits: Code reusability
• Interfaces: Defining contracts
