1. It must be "$this->" and not "$this - >". 2. Documentation can be found here: http://de.php.net/manual/en/language.oop.php

What is the symbol "- >" and is $this something only used in classes?

Yes. Inside a method you can use "$this" to reference the current object in which the method was called. The "->" operator is not specific to "$this". It is generelly used to call methods or access properties of an object.
