Instantiate a directory object and loop through it with the dir->read()
call. As you loop through, populate a new multidemensional array or object
with the filenames, whatever other data, and the time.
$d = dir($the_dir_to_loop_thru);
$c = 0; // array counter
while($current_file = $d->read()) {
// don't want the dot files
if ($current_file != "." && $current_file != "..") {
$files[$c]['name'] = $current_file ;
// get the last mod time, we need it as a unix timestamp so we
// can sort it
$files[$c]['lastmod_time'] = strtotime(filemtime($current_file));
$c ++ ;
}
}
// now we need a sort function
function time_cmp ($a, $b) {
return strcmp($a['lastmod_time'], $b['lastmod_time']);
}
// sort the array
usort ($files, "time_cmp");
...and so forth
