PHP class

Class is a core concept of PHP Object Oriented Programming. We can say that class is a template for an object and object is an instance of a class. We use object and instance as the same thing. For  example, Human class, Bycicle class etc.

The General Form of a class

We use class keyword to define a class. So we can define PHP class by following way

class classname{
//Object state
// Object bahavior

A PHP class body is  enclosed by curly braces.

PHP class naming convention

Class body surrounded by curly braces {}
Class name starts with capital letter(It is not necessary but we use this convention in our tutorial)
We write all methods and variable within class.
