i decided to go ahead and sort my array of folder files for my mp3 player folder to give a more organize output to the viewer.

i am using

ksort($output, SORT_STRING | SORT_FLAG_CASE);
from the ksort docs i take it we can use the flags from sort but im really not noticing any difference in the listing between using just SORT_STRING or adding the SORT_FLAG_CASE is this fairly normal. I cant really see where the SORT_FLAG_CASE is doing anything at all.

My songs titles are mixed upper and lower case.
