What is object-oriented programming?
Object-oriented programming combines a group of data attributes with functions or methods into a unit called an “object.” Typically, OOP languages are class-based, which means that a class defines the data attributes and functions as a blueprint for creating objects, which are instances of the class. Popular class-based OOP languages include Java, Python, and C++. Multiple independent objects may be instantiated—or represented—from the same class and interact with each other in complex ways.
A simple example would be a class representing a person. The person class would contain attributes to represent information such as the person’s age, name, height, etc. The class definition might also contain functions such as “sayMyName” which would simply print that person’s name to the screen.
A family could be constructed by instantiating personal objects from the class for each member of the family. Each person’s object would contain different data attributes since each person is unique.
Advantage of oops.
Object-oriented programming has several advantages over procedural programming:
- OOP is faster and easier to execute
- OOP provides a clear structure for the programs
- OOP helps to keep the PHP code DRY “Don’t Repeat Yourself”, and makes the code easier to maintain, modify and debug
- OOP makes it possible to create full reusable applications with less code and shorter development time
Object-oriented programming uses objects, but not all of the associated techniques and structures are supported directly in languages that claim to support OOP. It performs operations on operands. The features listed below are common among languages considered to be strongly class- and object-oriented (or multi-paradigm with OOP support), with notable exceptions mentioned.,,,
