For this tutorial, you should understand a few PHP basics: functions, variables, conditionals and loops. To make things easy, the tutorial is divided into 22 steps. Step 1: First thing we need to do is create two PHP pages: index.php class_lib.php OOP is all about creating modular code, so our object oriented PHP code will be contained in dedicated files that we will then insert into our normal PHP page using php ‘includes’. In this case, all our OO PHP code will be in the PHP file: class_lib.php OOP revolves around a construct called a ‘class’. Classes are the cookie-cutters / templates that are used to define objects. Step 2: Create a simple PHP class (in class_lib.php) Instead of having a bunch of functions, variables and code floating around willy-nilly, to design your php scripts or code libraries the OOP way, you’ll need to define/create your own classes.

Example Here is an example which defines a class of Books type − php class Books { /* Member variables */ var $price ; var $title ; /* Member functions */ function setPrice ( $par ){ $this -> price = $par ; } function getPrice (){ echo $this -> price . " " ; } function setTitle ( $par ){ $this -> title = $par ; } function getTitle (){ echo $this -> title . " " ; } } ?> The variable $this is a special variable and it refers to the same object ie. itself. Creating Objects in PHP Once you defined your class, then you can create as many objects as you like of that class type. Following is an example of how to create object using new operator. $physics = new Books; $maths = new Books; $chemistry = new Books; Here we have created three objects and these objects are indep...
