Lesson 14 - Interfaces in PHP
In this object-oriented programming lesson, we'll teach you how to use interfaces and the instanceof operator.
Lesson 15 - Interfaces and abstract classes in PHP
In this lesson, we'll keep going with interfaces as well as introduce you to abstract classes. You'll learn to implement and delegate interfaces.
Lesson 16 - Putting PHP interfaces into practice - GuestBook
In this lesson, we'll put our knowledge of OOP in PHP to the test by using interfaces to create a guestbook and modular captchas.
Lesson 17 - Guestbook in PHP - continuation
In this lesson, we're going to finish our PHP guestbook and change it's captcha implementation to image-based responses using our modular interface.
Lesson 18 - Exceptions in PHP
In this tutorial, we're going to cover what exceptions are in OOP. We'll show you how try-catch blocks work and how exceptions make PHP apps more readable.
Lesson 19 - Exceptions in PHP pt. 2
In tutorial, we'll explain the relationship between exceptions and OOP design, the types of built-in PHP exceptions, and how to react to exceptions.
Lesson 20 - Custom exceptions in PHP, propagation and the finally block
In this tutorial we're going to create our own exceptions, we'll explain propagation of exceptions and finally block.
Lesson 21 - Practicing PHP exceptions - Finishing the contact form
In the tutorial, we're going to finish our contact e-mail form in PHP using OOP using exceptions to handle user errors and finish up with exceptions.
