Working with $_GET and $_POST in PHP
This course will show you how to work with PHP Superglobals such as $GET and $POST while using a security-conscious mindset. External inputs, like HTML forms, are considered a security vulnerability so you should always filter inputs and escape outputs. Using PHP Superglobals when using external inputs such as HTML forms, cookies, sessions, and web servers will give you a security-conscious mindset that you can apply to all of your projects.

Object-Oriented PHP Basics
At a glance, object-oriented programming can appear to be far more complex than simple procedural, or inline, code. However, this doesn’t have to be the case. Because object-oriented programing is similar to the way human beings perceive the real world, using the object-oriented approach, can help you visualize the solution to a problem more easily. Object-oriented programming, or OOP for short, is a style of coding that allows developers to group similar tasks into containers. In PHP, containers are defined using classes. A class contains all the functions and variables that describe an object.

Designing Interfaces in PHP
An interface is a type of contract that assures that certain abilities are available on on a particular object class. We'll write and extend multiple interfaces, then implement them to design and match functionality. Interfaces do not store any implementation details themselves. To share implementation details between classes, we harness the power of inheritance. Abstract classes prevent a parent class from being directly instantiated, while at the same time defining methods that MUST be implemented in any extending children. This course will combine interface contracts with class hierarchy to leverage the benefits of each concept. We'll explain the differences between interfaces and abstract classes, and give you the knowledge you need to build and implement both in your own projects.

Basic Exception Handling with PHP
Exceptions are the object-oriented approach to handling errors. An exception is an object that is “thrown” by your application in the event that something goes wrong. They allow you to customize how a program handles errors, and gracefully degrades an application.

Object-Oriented PHP
Object-Oriented Programming allows groups of people to work together more easily. By grouping data and functionality into objects we also provide a structure for testing individual pieces. In this 13-hour Track, you'll learn the modern approach to Application Development in PHP using Objects, Templates, Dependency Management and 3rd Party Packages.
We'll start things off by building a basic PHP website. The site, a media library, will allow you organize and display your Books, Movies and Music, and you'll learn how to use PHP to handle inventory, reuse code, and manage email and form data. Our course on $_GET and $_POST will follow afterward and show you how to use these commands to run PHP more efficiently.
Next, we'll dive headfirst into Object-Oriented PHP. Object-oriented programming lets us group data and functions into a specific topic or piece of functionality, which in PHP is called a class. We'll explore the ways a class allows us to work with data, and use this knowledge to build a simple cookbook app with recipes.
In the next part of the Track, we'll learn how to combine interface contracts with class hierarchy to leverage the benefits of each concept. Then we'll cover PHP7, basic exception handling, and dependency management. Finally, we'll learn about the Laravel framework and how to use it with PHP.
Let's master the basics of Object-Oriented PHP together!
