<?php 
class Dog { 
    function __construct($name='No-name', $breed='breed unknown', $price = 15) { 
        $this->name = $name; 
        $this->breed = $breed; 
        $this->price = $price; 
    } 
} 
$aDog = new Dog(); 
$tweety = new Dog('A', 'a'); 

printf("<p>%s is a %s and costs \$%.2f.</p>\n",
