Object Oriented PHP
In object-oriented programming, a class is a blueprint for creating objects (a particular data structure), providing initial values for state (member variables or attributes), and implementations of behavior (member functions or methods). The class is a blueprint that defines a nature of a future object.
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 PHP basics 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.
PHPenthusiast is tailor-made for developers who are serious about mastering Object-oriented PHP. We not only provide easy-to-understand and concise tutorials, but also coding exercises to practice the newly acquired skills. By doing so, we make the learning process as fast and smooth as it can be.
PHP follows the organizing principles of functional, procedural, imperative, and object-oriented programming. You can use any of them or even a mixture of these programming paradigms. In this article, you will look into the OOPs methodology introduced in PHP. OOPs concepts in PHP can help the developers develop real-world applications that support reusability and are dynamic and complex in nature.
Object-Oriented Programming or simply OOPs is a programming approach or paradigm that gives its prime consideration to the data and its associated functions. It uses the concept of wrapping up the data as an object-entity having its associated properties, to provide higher security and less exposure to the data. As nothing is more important than the data itself, this approach is highly in use and widely accepted by programmers worldwide. The programming languages that do not support OOPs methodologies and their concepts are slowly getting deprecated, and the languages that are now being developed, support OOPs and are the extended version of object-oriented programming.
To relate programming with the real world, this methodology considers everything in the world as an entity or an object, and every object has some of its attributes or properties. So, the concept of the classes and objects can be applied to model an entire application. The overall development of an application in an object-oriented perspective can be summarized as:
The PHP programming language is based on the paradigm of Object-Oriented Programming (OOPs). Object-Oriented Programming is an umbrella under which the features of Object-Based programming resides. Meaning, it consists of all the characteristics of object-based programming and gets the better of its limitations by executing inheritance so that through programming, you can solve the problems based on real-life situations. Object-oriented programming was created to get better at the drawbacks of usual programming techniques. The OOPs concepts in PHP have been developed on some concepts that make it achieve its aim of getting the better of the drawbacks or deficiency of usual programming techniques.
When you define a class, with all its data members and member functions, then every instance or object of that class will occupy the memory equal to the memory allocated to the data members of that class. For eg: if a class has been allocated 10 bytes of memory for its data members, and if there are three objects of this class, namely obj1, obj2, and obj3, 10 bytes of memory will be allocated to each of the objects.
A module is a separate unit in itself. Hence you can execute a separate module as it is connected to other modules in some manner. All the modules act together as a single unit to ach
