Make sure here that you use the form of break tag that matches your 
doctype.

What array? At the moment you're working with a directory handle, from 
which you're reading one filename at a time. They come in whatever order 
the underlying os code delivers them.

If you want them sorted, read them in to an array and sort it, and then 
output the array in order, but at the moment, in your code, there is no 
array.

Without testing, the following might work:

<?php

$files = array();

if ( $handle = opendir ( '../audio/1960/' ) ) while ( false !== ( $entry 
= readdir( $handle ) ) ) $files[] = $entry;

sort( $files );

foreach ( $files as $file ) echo "{$file}<br>\n";

?>
