PHP & OOP: The introduction

Object-oriented programming is an approach to designing modular, reusable software systems.

Just like C, PHP was started out as a non object-oriented programming language.

Started in version 4, some basic elements of object oriented features were added.

And in version 5, especially from v 5.3, it started to support most features of object oriented methodology.

In some of our earlier examples, we have used object oriented style of programming.

You can refer to this example where I have used:

$mysqli = new mysqli('localhost', 'root', '', 'allartist')

We could write those code in procedural style but learning about OOP will open up a whole world where we could reuse OOP code written by others.
