Replace your call to sort with something like this:

usort($folders, function ($a, $b) {
    return strnatcmp($a['name'], $b['name']);
});

Additionally you might want to reduce your code complexity by using DirectoryIterator or scandir

Without knowing your error message, no one can help you. The code posted should work. Example: http://3v4l.org/gc2qg – Rangad Dec 04 '14 at 17:06
You deleted to much. The way your code currently stands will never call your function. The line that used to be above the call to `sort` should've remained. Add the `$folders = folderlist();` back before the call to `usort`. – Rangad Dec 04 '14 at 17:13
well i change again code and check on localhost it is showing this error Parse error: syntax error, unexpected T_FUNCTION in /in/qsaZX on line 24 and i also check on my website it is showing simple listing and also my website web it is showing error with simple listing Warning: sort() expects parameter 2 to be long, object given in /home/user/public_html/dir.php on line 26 – user1796164 Dec 04 '14 at 17:23
If you got unexpected T_FUNCTION you either messed up while copying the code or you use an (very very) outated version of php on your localhost. For the second error: Why do you call sort? If you want to use the code posted you need to use `usort`. – Rangad Dec 04 '14 at 17:35

You should try using scandir(). By default, scandir() will sort files alphabetically:

$dir    = './';
$files1 = scandir($dir);

print_r($files1);
