Resolved. I posted the corrected code below for traversing a 2D Array that uses incremented integers as keys. Maybe it will help someone. for($j=0; $j < [B]count($slideShowArr)[/B]; $j++){ for($k=0; $k < [B]count($slideShowArr[$j])[/B]; $k++){ print $slideShowArr[$j][$k]. ", "; } print "<br>"; } Code (markup):
