[dbs] Problem mit DB - Objekten; Beispiel aus dem Buch: Web Database Application with PHP and Mysql

[j.kuehne at sign-tronic.ch]

Kann mir jemand weiterhelfen mit den Fehlermeldungen. Irgendwie scheint $connection keine Objekt der Klasse DB zu sein. Wobei $connection = DB::connect($dsn, true) erzeugt wird, aber eben mit der Meldung; Error: "Non-static method DB::connect() should not be called statically" (error #2048).

Vielen Dank

Gruss,Jörg
