Basically you have a TYPO3 *extension*, not a *standalone* application.

the Web. TYPO3 is calling you, meaning it prepares so-called "parent
object" ($pObj) and injects it to your class so that you can work with
As said, consider reading a book about TYPO3 development or at the very
least install a proper development environment with some IDE (PhpStorm,
NetBeans, ZendStudio, ...) and Xdebug to let you step through your code
and analyze the stack trace, will help *a lot* to let you understand the
