Who Is This Book For. This is not a beginner's guide to OOP PHP. We are not going to cover the syntax of classes or the difference between. PHP and Object-Oriented Programming All the forces in the world are not so powerful as an idea whose Selection from Learning PHP Design Patterns [ Book]. This article is a listing of PHP books that have been released in the last learn the foundations of Object Oriented Programming, some design.
So we take full advantage of this behaviour, by initializing many things through constructor functions. You can pass as many as arguments you like into the constructor function. Following example will create one constructor for Books class and it will initialize price and title for the book at the time of object creation. We can initialize these two member variables at the time of object creation only.
You can release all the resources with-in a destructor. Inheritance PHP class definitions can optionally inherit from a parent class definition by using the extends clause. Automatically has all the same member functions as the parent, which by default will work the same way as those functions do in the parent. Following example inherit Books class and adds more functionality based on the requirement.
Function Overriding Function definitions in child classes override definitions with the same name in parent classes.
In a child class, we can modify the definition of a function inherited from parent class. In the following example getPrice and getTitle functions are overridden to return some values. If you wish to limit the accessibility of the members of a class then you define class members as private or protected. Private members By designating a member private, you limit its accessibility to the class in which it is declared. The private member cannot be referred to from classes that inherit the class in which it is declared and cannot be accessed from outside the class.
A class member can be made private by using private keyword infront of the member. Protected members A protected property or method is accessible in the class in which it is declared, as well as in classes that extend that class. Protected members are not available outside of those two kinds of classes. A class member can be made protected by using protected keyword in front of the member.
Different implementors can implement those interfaces according to their requirements. You can say, interfaces are skeletons which are implemented by developers. Once you declare a constant, it does not change.
It is declared with the keyword const, and under no circumstances can it be changed to anything other than 1. Abstract Classes An abstract class is one that cannot be instantiated, only inherited.
It is not legal to have abstract function definitions inside a non-abstract class. Static Keyword Declaring class members or methods as static makes them accessible without needing an instantiation of the class.

As other reviewers have stated, this is defiantly not a book that will teach you object oriented programming, nor, have I found a book that teaches all the concepts of OOP and how to program php in conjunction with one another.
If you already know OOP, but need to learn how to define classes etc, in PHP, this is an excellent resource and a good read.
I'll agree with others and say that Mike Zandstra's book covers this topic better. The author goes through one example throughout the book using classes to manipulate a file directory without fulling explaining how some of the topics work. For example, the author gives a code example, say in english what it's doing to the files, but doesn't explain how. I just wouldn't use this book to learn it.
One person found this helpful. I have already learned OO concepts and programming through various classes. This book has a lot of good information that was exactly what I needed.
The reading can be a bit awkward at times, and requires reading ahead to understand back? In other words things are used before their explained, and sometimes their used to explain other things, so you must eventually double back. All in all if you are a PHP programmer wanting to upgrade, its worth the price.
Thank you very much My views, however, are from a longtime web developer. This book is great whether you are an experienced coder or a beginner.
I've been using php for a few years now, and i picked this book up, just to have under my belt, and wow. It really gets into PHP5 where the world of web should be headed. A few key features, is, he gets deep into OO in PHP5, which is nice, and gives you examples and sample codes. Writes it like a pro, so anyone can follow a long.
He even talks about a few items from the SPL. Like he said, PHP is a victim of its own success.
Object-Oriented PHP is really a technical brief that seems to fall short of its own ambitions. Lavin summarizes the reasons for the changes and reviews basic concepts of OOP.
He then develops some classes for an application that draws images from a database and displays thumbnail images. In some places the PHP 4 equivalent code is provided for study. It is a terse and sometimes bumpy ride. The book's conversational tone is appropriate for fellow geeks, but I found it more distracting than reassuring. There are some summary apologies, for example, that make the chapters seem like they were transcribed from tape.
Rather than go back and match the introductory objectives to the text, a summary or two admits things didn't quite work out as planned. Ok, let's say there was no time to fix it. How does calling attention to it help? Because the book is so short, the author glosses many concepts, frequently referring to web sites for technical details and tutorials.
Once or twice he refers to a well-known author e.
Again while this is appropriate for a peer audience, it also needlessly puts the book out of reach for some readers. It seems to me the book once had a too-ambitious outline. The reader would be right to feel misled. I doubt a skeptical or demanding reader will like this book. Beginners will almost certainly get lost early and often. See all 20 reviews.
