Stephen,

One thing to watch out for: unordered filesystems.  ReiserFS in 
particular does not maintain its directories in any ordinary sorted 
order.  If you want the file names in order, follow the above code block 
with one of:

natcasesort( $arrStyles );  // My favorite for directories [1]
sort( $arrStyles );         // [2]
asort( $arrStyles );        // [3]

Hope this helps,

Phil
