I think array_multisort is supposed to do this but I couldn't get it to
work.
Have a look at the usort call in the following routine;
// Reads a directory and puts filenames into a array sorted by date
function GetFiles ($DataPath, &$files, &$nfiles) {
$handle=@opendir($DataPath);
if ($handle) {
$nfiles = 0;
while (false!==($file = readdir($handle))) {
if ($file != "." && $file != ".." ) {
$files[$nfiles][name] = $file;
$files[$nfiles][date] = filemtime($DataPath."\\".$file);
$nfiles++;
}
}
if($nfiles>1){
usort($files,
create_function(
'$a,$b',
'return $a["date"]==$b["date"]?0:($a["date"]<$b["date"]?1:-1);')
);
}
closedir($handle);
}
}
