Object-Oriented PHP: Concepts, Techniques, and Code by Peter Lavin

The simpler object model of PHP makes it the ideal language for an introduction to object-oriented programming. For the uninitiated, this guide to the latest version of PHP offers a speedy introduction to object-oriented programming, including a thorough explanantion of class as well as coverage of constructors, destructors, inheritance, polymorphism and interfaces. Peter Lavin runs a web development firm based in Toronto, Canada, and he writes regularly on all things tech. He has been published in a number of magazines and online publications, including UnixReview. All rights reserved.

With the basics out of the way, we'll now focus on object-oriented JavaScript OOJS — this article presents a basic view of object-oriented programming OOP theory, then explores how JavaScript emulates object classes via constructor functions, and how to create object instances. To start with, let's give you a simplistic, high-level view of what Object-oriented programming OOP is. We say simplistic, because OOP can quickly get very complicated, and giving it a full treatment now would probably confuse more than help. Objects can contain related data and code, which represent information about the thing you are trying to model, and functionality or behavior that you want it to have. Object data and often, functions too can be stored neatly the official word is encapsulated inside an object package which can be given a specific name to refer to, which is sometimes called a namespace , making it easy to structure and access; objects are also commonly used as data stores that can be easily sent across the network. Let's consider a simple program that displays information about the students and teachers at a school. Here we'll look at OOP theory in general, not in the context of any specific programming language.

NET, Ruby, and Swift. Object-oriented programming OOP is a relatively complex subject to master. However, Object-oriented programming OOP promotes good design practices, code portability, and reuse but it demands a change in the thinking process to be fully grasped. For that reason, programmers venturing into Object-oriented programming are advised to actively resist the temptation to start learning a particular programming or modeling language before they have a grounded understanding of Object-oriented programming concepts. A good grasp of Object-oriented programming will make everything every programmer relatively easy to understand and aids better communication among their team mates.

For the uninitiated, this guide to the latest version of PHP offers a speedy introduction to object-oriented programmimg, including a thorough explanation of classes as well as coverage of constructors, destructors, inheritance, polymorphism, and interfaces. Working within the context of concrete examples, the book begins with code compatible with PHP 4 and 5, and then focuses on object-orientation in PHP 5. The author's practical approach uses numerous code examples, which will help developers get up to speed with object oriented PHP quickly.

We can imagine our universe made of different objects like sun, earth, moon etc. Similarly we can imagine our car made of different objects like wheel, steering, gear etc. Same way there is object oriented programming concepts which assume everything as an object and implement a software using different objects. You can think of a class as a template for making many instances of the same kind or class of object.

Object-Oriented PHP: Concepts, Techniques, and Code by Peter Lavin

This book or coding bootcamp, whatever you want to call it, is designed for absolute beginners who have not yet made their hands dirty with code. However, if you plan to be a web developer, learning a good dynamic programming language, then this book is for you. PHP 7 is custom-made for you to build from simple to complex web application. It is equivalent to an intensive coding bootcamp for three months designed for Absolute Beginners.

The simpler object model of PHP makes it the ideal language for an introduction to object-oriented programming. For the uninitiated, this guide to the latest version of PHP offers a speedy introduction to object-oriented programming, including a thorough explanantion of class as well as coverage of constructors, destructors, inheritance, polymorphism and interfaces. In this easy to follow guide, the author teaches by example, and couples new concepts with snippets of example code which are available for download from the books companion website. Peter Lavin runs a web development firm based in Toronto, Canada, and he writes regularly on all things tech.

Using PDO unbuffered behavior is easily reproduced. Our SQLite application uses buffered result sets in cases where we need to know that there are records returned or where the specific number of records is required. To buffer records using PDO you can use the fetchAll method of a statement to return an array.

Defining PHP Classes

PHP started as a un-organized programming language to build things quickly without a solid design and as such made it easy to learn. It is gradually evolving from a language that sucks to a robust language following in the footstep of most strongly typed programming languages like C , Ruby, ASP. One paradigm common with most dynamically typed languages is the support for Object-oriented programming OOP. Objects, which are usually instances of classes, are used to interact with one another to design applications and computer programs. I had no programming background prior to PHP. I found it very difficult at first, understanding OOP terminologies, syntax and how to code with it. They explained OOP in simple, easy to understand English.
