Class

             Class

Ø      A class is defined by using the class keyword, followed by the name of the class and a pair of curly braces ({}). all its properties and methods go inside the braces:

      A PHP class is a group of values with a set of operation to manipulate this values.

Ø               class is the blueprint of objects.

            }

       function method_name(parameter list)

            {

              body of method;
