    public function sayHello() {
	 print "Hello ($this -> getName()}!";
	}
	
	public function getName () {
     return $this -> _name;
	}
	
	public function setName($name) {
	 if (!is_string($name) || strlen($name) == 0) { 
	  throw new Exception ("Invalid name value");
	  
	  }
	  $this -> _name = $name;
  }
 }
?>

<?php

  require_once('class.Demo.php');

  $objDemo = new Demo();
  $objDemo->name = 'Steve';
