A Object Oriented Programming Lesson For Beginners
In this article I will go over object oriented programming in relation to PHP. This article will be especially useful to those who already have a simple knowledge of programming and variables. You should know what a variable is, and you should also know about the different types of variables.
When you read this information, it is important to remember that the terms used for other programming languages may be different. It is the overall concepts that you will want to pay close attention to. One of the most powerful aspects of OOP is that the code which is generated by a programmer can be reused and placed in bundles.
Code which can be reused is extremely important. The reason for this is because it will save the programmer both money and time. In addition to this, the code will be efficient. The bundles of code that can be reused can be utilized to create what is named an object. The object can be changed in a number of different ways, and it can also carry out various processes. Before you can construct an object, you will need to create a template which is related to the object. The proper name for this template is a class. In a programming language like PHP, the classes will be defined by the keyword named "class."
For example, if you decide to create a template for dogs, the class would be called dogs. You would want to design a template which will define the typical dog. There are a number of things a dog can do. The dog can bark, eat food, or wag its tail. In order for the dog to do these things, you will need to add a function, which may also be known as a method. Once you have added the functions, the dog will be able to perform some simple actions. In addition to functions or methods, you can also give an object properties. The property that will be given to the dog will be placed within the class. The properties of a dog could be its name, fur color, or build. There are two terms that you will want to become familiar with in object oriented programming, and these are initialization and instantiation.
Instantiation occurs when an object is generated within your code. It is important to keep in mind that templates and classes are the same thing. They are similar to diagrams. While the diagram of a home isn’t the actual home, it is the design that will be used to build the home. The instantiation process will occur when the house is actually built. Initialization will occur when you give a value to a variable for the first time. It is important for you to know the difference between instantiation and initialization. Once you have created variable within the template, you will next need to assign something to the dog object. If you don’t do this, you will have variables that are empty.
The variables will need to be initialized. You will assign values to the variables in your class with this keyword. If you are working with a function that has the same name as the class, you will need to construct an instance of the object. Once this has been done, the function may be called as soon as an instance of the object is created. The name of this type of function is a constructor. It is also possible for functions to take what is called parameters. These are values that are given to the function. The function will take these values and attach them to the variables.
Object oriented programming is a powerful paradigm that has changed the way computer applications are designed. Instead of a taking an approach that is subject oriented, OOP has taken an approach which is object oriented. A large number of modern languages are using this concept, and some of these include PHP, Java, Lisp, and Pascal. If you wish to become adept that using these programs, it is important for you to understand fundamental concepts that make up object oriented programming. Once you have done this, you will be able to master any OOP language.
