$fmtime = filemtime($d);
if (!array_key_exists($fm,$dir)) $dir[$fm] = array();
$dir[$fm][] = $d;
This would give you an array indexed by filetime containing arrays of
filenames. You may try and see if the last line is enough on its own, but I
believe it once happened to me that it failed to create a two levels deep
array of arrays in just one shot, that's why the second line. Alternatively
you could use the filename as key of the second array and store in it any
information as data, for whatever you might need:
$dir[$fm][$d] = some data related to $d.

Subject: Appending into associative arrays
I want to sort directories according there modification time and thought
accociative arrays would be perfect. But when I add an element like
$dirs = array (filemtime($d) => $d)
the previous ones are lost. I tried array_push but that doesn't seems to
work, at least I always get syntax errors. Next try was array_merge(array
(...)). So what next?
