sorting numbers

[Davide]

Hi all..

I'm trying to sorting a file in a directory.
It works well but it sorts me the number in this way:

1
10
11
2
20
21
....

is there a way to sort in this way?
1
2
3
...
10
11
12

this is my code:

<?php
if ($handle = opendir('/home/davide/')) {
$files = array();
while (false !== ($file = readdir($handle))) {
if (($file != "." && $file != "..") AND (eregi($select,$file)))
$files[] = $file;
}
closedir($handle);
sort($files);
foreach($files as $file) {
$ext = substr(strrchr($file, "."), 1);
if ($ext == 'txt') {
$idx = str_replace('.txt', '', $file);
echo "$idx";
}
}
}
}
?>

Change to natsort($files);
