I need this php script to pull files alphabetically?

I have this script that pulls files from a drop down to play automatically on my site. how do I get it to play them in order? they are in order in there folders but wont play in order on the player.

<?php
require_once('includes/config.inc.php'… 

$page_title = 'Music';



// Start output buffering:

ob_start();



// Initialize a session:

session_start();



// Check for a $page_title value:

if (!isset($page_title)) {

$page_title = 'User Registration';

}



// If no first_name session variable exists, redirect the user:

if (!isset($_SESSION['first_name'])) {



$url = BASE_URL . 'index.php'; // Define the URL.

ob_end_clean(); // Delete the buffer.

header("Location: $url");

exit(); // Quit the script.



}

?>

<?php 

$mp3_list = '';



if ( !empty($_POST["musicdir"]) ) { //Get folder info

$dir = $_POST["musicdir"];

$base = $_POST["basepath"];

$wbase = str_replace('\\', '/', $base);

$pattern = "\.(mp3)$";



if ( strlen($dir) > 0 ) {

$wdir = $_SERVER['DOCUMENT_ROOT'] . $base . '//' . $dir; //made a change here



if ( file_exists($wdir) && is_dir($wdir) ) {



if ($handle = opendir($wdir)) {

while (false !== ($file = readdir($handle))) {



if ($file != '.' && $file != '..') {



if( eregi($pattern, $file) ) {

//echo $wbase . '/' . $dir . '/' . $file . "
";

$mp3_list .= $wbase . '/' . $dir . '/' . $file . ',';

}

}

}



closedir($handle);

}

}

} 

}



function loadMusic($path) {

$out = '';



if (strlen($path) > 0) {

$path = $_SERVER['DOCUMENT_ROOT'] . $path;



if ( file_exists($path) && is_dir($path) ) {

if ($handle = opendir($path)) {

while (false !== ($file = readdir($handle))) {

if ($file != '.' && $file != '..') {

if ( is_dir($path . '//' . $file) ) { // Only list directories 

$out .= '<option value="' . $file . '">' . $file . '</option>';

}

}

}

closedir($handle);

}

}

}



return $out;

}

This should be easy enough to do.

Instead of reading the filenames and immediately adding them to your $mp3_list as you do below:

$mp3_list .= $wbase . '/' . $dir . '/' . $file . ',';

Add them to an array instead:

$mp3_array[] = $wbase . '/' . $dir . '/' . $file . ',';

Then after you close your while loop sort your array like so:

sort($mp3_array);

Follow this with another loop to add the contents of $mp3_array to $mp3_list:

for($i=0; $i <=count($mp3_array); $i){
     $mp3_list .= $mp3_array[$i];
}

Use whatever code you deem fit for your loops and arrays as the above example is easy to read but not well optimized.

Hope this helps,
