The essentials of Object Oriented PHP: Learn, practice, and apply
Over 80% of websites are now written in PHP, making it more important than ever for web developers to master this programming language. Although the basics of PHP are easy to learn, it is the knowledge of Object-oriented PHP that separates the professionals from the hobbyists.
When using Object-oriented programming, we organize the code in an efficient way, so it is easier to work with, develop and upgrade. Due to its many benefits, developers who master the craft of Object-oriented PHP are a hot commodity in the job market among companies and enterprises that have a need for advanced online applications.
But this does not tell the full story. Consider the following facts :
- Procedural programming is inefficient
- PHP frameworks rely on object oriented PHP
- Drupal and other CMS systems are now object oriented
- PHP libraries are almost exclusively written in object oriented PHP
Let's expand on the first fact as it is the mo st important one - everything else flows from it, i.e. object oriented programming is gaining popularity because it is more efficient. There are great applications written in the procedural style of PHP, but even the best end up in spaghetti code where functions and variables are mixed together. Add in HTML, CSS and JavaScript to this mix and the code becomes something that is, well, inefficient. Object oriented code is more organized. Distinct units are created for a single purpose. This means it is easier to find things in the code (ending those days of spending hours trawling through lines of spaghetti code to find a single element). It is also easier to add, replace or remove parts of code as it only has to be done once. Finally, object oriented programming gives the opportunity to developers to integrate code libraries from other resources.
So, back to the original question, why bother learning object oriented PHP?
The answer is:
- It is increasingly common
- Developers with this skill earn more
- The code they write is better
- They can integrate their code with code written by other programmers and with libraries from the thriving PHP community
Programming in object oriented PHP requires a different way of thinking. That is why it is important to get an understanding of the fundamentals.
Who is this book for?
Obviously, this book is for procedural PHP developers who want to improve their skills and take their development skills to a new level. It is also for programmers who have a very basic understanding of object oriented PHP, but who want to learn it properly and get more practice.
Getting the most from this book
As already established, this book is designed for existing programmers who want to expand their skill set with object oriented PHP. As a result it is written in a learn-then-practice form.
Every principle, idea or process is described in a simple and concise way. And demonstrated with the simplest code examples. The flow is also structured so that the reader develops hooks to hang additional knowledge as their understanding grows and develops.
Once the foundations are laid, the learner gets a plethora of opportunities to practice and bring the material to life. In the practice opportunities, the learner is guided through the process of writing code examples that are based on what he has just learned. This is where proper understanding develops as the learner repeatedly gets a chance to practice what he has learned.
It is not a passive learning tool. This book is designed to give developers knowledge and skills in object oriented PHP quickly. That is achieved through active learning where programmers think for themselves while reading the explanations and examples and practicing the material.
So, to get the most from this book, approach it with an open mind and be ready to get inv olved. By doing this you will get a good understanding of object oriented PHP with sufficient knowledge and confidence to apply it practically in your work.
