From PHP5, you can also write PHP code in an object-oriented style.Object-Oriented programming is faster and easier to execute
OOP stands for Object-Oriented Programming.
Procedural programming is about writing procedures or functions that perform operations on the data, while object-oriented programming is about creating objects that contain both data and functions.
Object-oriented programming has several advantages over procedural programming:
Classes and objects are the two main aspects of object-oriented programming.
Look at the following illustration to see the difference between class and objects:
Fruit
Apple
Banana
Mango
Another example:
Car
Volvo
Audi
Toyota
So, a class is a template for objects, and an object is an instance of a class.
When the individual objects are created, they inherit all the properties and behaviors from the class, but each object will have different values for the properties.
