Actually, when you're inside a class method you do need to use $this-> to refer to class variables. If you don't, it's assumed you're referring to a variable local to that method. That is, when you say $bar = "foo"; inside a class method, that doesn't automatically create a class variable. So if we have class Foobar { var $foo; Foobar() { $this->foo = 'something'; } function myfunc() { // These are two different variables. $bar = 'foo'; $this->bar = 'foo'; echo $this->foo; } } There are some other good examples in the Classes and Objects documentation at http://www.php.net/manual/html/oop.html HTH, Matt
