class, object, method, and final are all part of object-oriented programming. In object-oriented programming, there is an important concept called Inheritance that allows one class to inherit properties of another class and even have the ability to replace the original behavior given.
There are cases where we need to prevent the class from being inherited. The task can be accomplished by using the final keyword, which prevents any class or method from being used. The final class is a class that cannot be extended by other classes.
Child classes are not included in a Class that is declared with the final word. A class can be declared final if the final word is before the class. The final class name is given in the Syntax.
For Java developers, the 'Final' is not used for class constants. The word 'const' is used. If the class.
As the class is already final, the final constant is redundant.
What is abstract class in PHP?
What is an abstract class? An abstract class is an interface between a regular class and a pure interface. There is a special case of abstract classes where all methods are abstract.
The features of abstract class are related to object oriented techniques. We will learn about the implementation of abstract class. A class can be declared as abstract by affixing the name of the class with the abstract keyword. The class that contains abstract methods is known as abstract class.
The abstract class has name and arguments, and no other code.
The abstract class Dumper has a string that says " PHP abstract class is awesome!". awesome!".
An abstract class is defined by you.

What is static class in PHP?
A static class is a class that is instantiated in a program. It must have a static member that is assigned to a variable on a child class.
One of the most valuable aspects of the methods and variables is the static classes. Let's dive into this article right away because it will be the game-changing article in your affiliation with static classes.
It is used to make functions and classes static. I will tell you why you might want to implement static functions and classes. You will understand how to make functions and variables within a class static, how to access these static members, and when to declare class members as static.
You can perform actions inside a static class. A static method is used to access the actions. It is.

What is static and final in PHP?
Only classes, methods, and constants may be declared as final. Private methods may not be declared final except for the constructor.
The third point seems to be missing from the PHP.
The last word is added to the code in version 5. The above statement about the final class can be proved if the final modifier acts while inheriting it.
It causes the fatal errors that occur on inheriting the final classes. The error is.
What is static is the main difference between static and final.
