Introduction to User Authentication in PHP
Do you want users to be able to interact with your site? Do you want users who are active participants in the content you provide? That interaction could be purchasing products or adding products to sell, leaving comments or providing blog posts. No matter which type of interaction your site provides to users, you'll need a way to authenticate those users. In this course we'll lay the foundation for keep your data safe and secure while building a platform for active participation.

PHP Basics
In this course I'll walk you through the basics of the language, ranging from basic statements to conditionals. We'll be creating a simple "Unit Converter" as well as a "Daily Exercise Program". We'll then finish up by combining those programs with HTML to create a personal webpage to demonstrate your skills.

PHP Functions
PHP Functions allow you to combine several statements of code into a 'function'. These functions can then be called by their given name, and all of the code contained will run and return the results. This will drastically help you clean up code and use less repetitive code.

Browser Persistent Data with PHP
With smartphones, smartwatches and even smart appliances, the internet of things has brought us into a world to rival sci-fi novels. We're no longer content with a simple search. We want context. We expect our devices to know our locations, preferences, desires and goals. We expect tailored suggestions, reminders and announcements. Most of the time we don't even realize how much our devices or websites are setup to assist us until our connection is broken or we try to use a different device, and all of a sudden our history and setting aren't there and it's so much harder to do or find anything. Users have come to expect so much and it's just getting worse. So what does that mean to you as a programmer? How can you make your own applications "user aware"? It starts with data persistence.

CRUD Operations with PHP
In this course we'll delve into the full spectrum of database interactions. Whether the application is an e-commerce, or social network site, or even a todo app on your phone, the data needs to change over time. CRUD is an acronym that refers to the four main operations that you'd want to perform on data in a database: Create, Read, Update, Delete.

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.

Environment Variables with PHP
In the lifecycle of an application, there are multiple environments such as Development, Testing and Production. Each environment may have its own unique sources and credentials that need to be managed and secured. Environment variables are accessible to any programming language, and allow applications to adapt to their environment while keeping credentials secure.

File Handling with PHP
PHP can do so much more than include files. In this course we'll explore reading and writing files from a directory. We'll also take advantage of built-in parsing functions for working with common file formats to read and write CSV, XML and JSON data.

Getting Started with PHP Unit Testing
For all us imperfect programmers, I have some great news. There are tools that can help you keep those mistakes from breaking your application. They can also help you find and fix bugs faster, while at the same time, preventing those bugs from ever coming back. Many of these tools revolve around testing.

Integrating PHP with Databases
Building a PHP-driven page is the first step in mastering PHP. The true power of PHP shines when you connect it to a data source like an API or a Database. To introduce you to databases, we'll use an example project -- a Personal Media Library application. We'll refactor this project by replacing an associative array with a database to provide a more robust and scalable tool to store the data in the media library. In the process, you'll learn how to use PDO -- a PHP extension to communicate with a database. You'll also learn about relational databases including how to search for data across multiple tables, as well as how to add common web site features like search forms and pagination.

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.

PHP Standards and Best Practices
PHP is a flexible language with a long history. Being such a popular language for so long means there is a lot of code out there. There are many ways to program in PHP, and not all of them are as safe, performant, or maintainable as some of the older educational materials might have you believe. Having so many options can be daunting to many developers as they grow from beginner to intermediate. Fortunately there are established best practices out there, and this course will help you learn about many of them.

Using the GitHub API with PHP
Application Programming Interfaces, or APIs, provide a method for connecting your site to a “third-party” web service. We'll use the GitHub API to explore how RESTful APIs allow us to retrieve and update information residing on an external system.

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.
