Visning af dir fortsat

Dette er et opfølgnings spørgsmål til tråd nr 564150

Jeg fik et svar om at man skulle ændre
if (!isset($path)) { $path = "./"; }

Nu har jeg kigget nærmere på det. Det viser sig at når man ændre det der hvor du siger, så kan man trykke på linket ../ og så se indholdet af mappen før. Hvordan kan jeg lave om på det?
