Practice It: PHP Classes and Objects

This is the repository for the LinkedIn Learning course Practice It: PHP Classes and Objects. The full course is available from LinkedIn Learning.

If you’re trying to become a more nuanced, successful PHP developer, you can’t overstate the value of expertise in object-oriented programming. That’s because PHP frameworks like Drupal, Symphony, and Laravel all require the same foundational programming skills. In this course, instructor Tammy Robinson gives you a practical overview of working with PHP classes and objects, two of the most important extensible concepts of procedural programming. Learn about creating classes and class instances, also known as objects, exploring a wide range of different access types, properties, and methods. Along the way, Tammy offers tips on using operators, constructors, inheritance, abstract classes, interfaces, and traits.

This course is integrated with GitHub Codespaces, an instant cloud developer environment that offers all the functionality of your favorite IDE without the need for any local machine setup. With GitHub Codespaces, you can get hands-on practice from any machine, at any time—all while using a tool that you’ll likely encounter in the workplace. Check out the Using GitHub Codespaces with this course video to learn how to get started.

Instructions

This repository has branches for each of the videos in the course. You can use the branch pop up menu in github to switch to a specific branch and take a look at the course at that stage, or you can add /tree/BRANCH_NAME to the URL to go to the branch you want to access.

Branches

The branches are structured to correspond to the videos in the course. The naming convention is CHAPTER#_MOVIE#. As an example, the branch named 02_03 corresponds to the second chapter and the third video in that chapter. Some branches will have a beginning and an end state. These are marked with the letters b for "beginning" and e for "end". The b branch contains the code as it is at the beginning of the movie. The e branch contains the code as it is at the end of the movie. The main branch holds the final state of the code when in the course.

When switching from one exercise files branch to the next after making changes to the files, you may get a message like this:

error: Your local changes to the following files would be overwritten by checkout:        [files]
Please commit your changes or stash them before you switch branches.
Aborting

To resolve this issue:

Add changes to git using this command: git add .
Commit changes using this command: git commit -m "some message"
