✔ Constructor initialisiert Klassenmember nicht

[Jungbluth]

Hallo,
ich habe eine Klasse geschrieben und diese scheint scheinbar den Constructor nicht richtig zu verarbeiten.
Wenn ich die klasse initialisiere kriege ich nicht nur den etliche Fehlermeldungen zu angeblich undefinierten Variablen, sondern scheinbar wird eine Variable auch fast initialisiert.

Siehe PHP: Die Grundlagen - Manual

Genau hinsehen und feststellen, dass du jeweils ein $ zu viel hast.
