You can use this function

function listdir_by_date($path){
$dir = opendir($path);
$list = array();
while($file = readdir($dir)){
    if ($file != '.' and $file != '..'){
        // add the filename, to be sure not to
        // overwrite a array key
        $mtime = filemtime($data_path . $file) . ',' . $file;
        $list[$mtime] = $file;
    }
}
closedir($dir);
krsort($list);
return $list;}

You can then loop through $list and echo accordingly.

Basically You can use the filemtime() function described here.
