Guided Notes
Object-Oriented PHP
Classes and objects, constructors and promoted properties, visibility, inheritance, abstract classes, interfaces, traits, static members, enums, and namespaces.
Classes and objects
Slide 1 / 5A class is a blueprint; objects are instances built from it:
class Product { public function __construct( public string $name, private float $price, ) {} public function price(): float { return $this->price; } } $pen = new Product('Pen', 1.5); echo $pen->name;
Constructor property promotion (PHP 8) declares and assigns properties in one place. $this refers to the current object; -> accesses its properties and methods.
