PHP - Advanced Features

Explore how namespaces organize PHP code to prevent naming collisions across libraries, enable using the same class names, and reference classes with backslashes in paths.

Create and use PHP namespaces to avoid class name conflicts by organizing code into namespaced files, using the use keyword and aliases to access a display class.

Explore interfaces in PHP: they contain no data or functionality and define behaviors through method signatures. Learn how to implement an interface in a class to enforce these signatures.

Learn how to create and use interfaces in PHP by defining an interface, implementing it in a class, and enforcing method signatures that require specific parameters like arrays.

Discover traits as a code reuse mechanism in PHP, enabling you to incorporate reusable code across multiple classes, combine multiple traits in one class, and overcome single inheritance limits.

Demonstrates creating and using traits in PHP by defining trait files, importing them, and applying multiple traits inside a class with the use keyword.

Explore abstract classes in PHP, including abstract methods and the abstract keyword, showing how base code provides a structure for child classes to implement or overwrite without direct instantiation.

Learn to create and use abstract classes in PHP by defining a base car class. Extend it with BMW, implement an abstract method, and access a protected brand via showBrand.
