This tutorial category contains all the tutorials related to Object-Oriented PHP.
In this tutorial, we will learn about Namespaces in PHP. Namespaces are mainly used to group classes that perform some similar kind of task. Furthermore, another benefit to using namespaces is we can use the same name for more than one classes in different namespaces. For example, suppose we have namespaces A and B both can have a …
In this tutorial, we will learn about Static Properties in PHP. Same as static methods we can declare static properties in PHP. We can access these static variables without creating an object of the class. Static properties can be declared using the static keyword. Please check out the following example program to know how to declare static …
In this tutorial, we will learn about Static Methods in PHP. As we know to call any method of class we must create an object of that particular class first. But we can call a static method without creating an object of the class. Creating a static method is easy as creating an instance method expect …
In this tutorial, we will learn about Traits in PHP. The trait is similar to a class but It isn't permitted to instantiate a Trait on its own. Traits are mainly used to declare methods that can be used in multiple classes. PHP only supports a single level inheritance(means we can inherit one class from another). But …
In this tutorial, we will learn about Interface in PHP. The interface gives the ability to programmer to define what public methods a class should implement. An interface can contain only abstract methods it means we only declare methods names in the interface and after that, we define the body of these methods in a …
In the dynamic world of PHP, abstract classes stand tall as powerful tools that allow developers to lay the groundwork for flexible and robust object-oriented programming (OOP) designs. These unique classes enable the creation of blueprints for other classes, fostering code reusability and promoting a structured development approach. In this article, we will delve into …
In the realm of object-oriented programming (OOP), method overriding is a crucial concept that empowers developers to modify and enhance the behaviour of inherited methods from parent classes. PHP, being a versatile and widely-used language, fully supports method overriding, providing developers with a powerful tool to create flexible and maintainable code. In this article, we …
Method overloading is a fundamental concept in object-oriented programming that allows developers to define multiple methods with the same name but different parameter lists within a class. PHP, being a versatile and widely-used programming language, fully supports method overloading, offering developers flexibility and convenience in their code implementation. In this article, we will explore the …
In this tutorial, we will learn about how to declare Constants in PHP class and fetch them using class objects. A constant is something like a variable used to store some value excepted the value of constants cannot be changed once it is declared. We can declare constants in PHP class using the const keyword. Please …
In this tutorial, we will learn about Inheritance in PHP. Inheritance is a mechanism in which we can inherit the properties and methods of one class into another. This helps us to create a new class that will have its own properties and methods and all the features of its parent class(from which the new class is inheriting features). …
