PHP 7 Object Oriented Programming

Object Oriented Programming Introduction

The Object Oriented programming provides an approach to eliminate the flaws encountered in the procedural approach. OOP divides the program into a number of entities called Objects. An Object is an instance of Class and Class is used to organize the data and functions together. Data is hidden and cannot be accessed by external functions.

The Main purpose of OOPS is to simplify the design, programming and most importantly debugging a program. If some piece of codes are written in multiple files, then instead of writing them again and again, it would be better to write in one place and call them when required. The maintenance of the code is also become easier, to modify particular data it is easy to identify which function to use. PHP5 has added supports for Object Oriented Programming language.

Advantages of Object Oriented Programming

  • Reusability - We can reuse the code by calling methods.
  • Reduce Complexity - OOPS helps in better programming design, transparent conceptualization promotes efficiency, modularity and reduces complexity.
  • Reduce Development Time - In OOPs, we can reuse the already defined components.
  • Maintainability - Each class is self contained. Therefore, OOP is easily maintainable.
  • Object Independence - Objects are independent of each other.
  • Data Security - Encapsulation is considered as data hiding that binds the data and methods into a single entity. So OOPS is used to hide the internal object details.
  • Modularity - This is achieved by dividing the complex part of the codes into well defined classes.
