    Here is the code I'm using... it is supposed to sort the results in alphabetical order... but it's not.

    <?php
$THUMBNAIL_FOLDER = "_thumbnails";
$HIDDEN_FILES[]	= "Thumbs.db";
$HIDDEN_FILES[] = "index.php";
$HIDDEN_FILES[] = $THUMBNAIL_FOLDER;
$THUMBNAIL_WIDTH = 200;
$THUMBNAIL_HEIGHT = 100;

// Image Output;
HandleImageOutput();

?>
<html>
<head>
<title>Index Of.</title>
<style>
body { background-color: #FCFFF0; font-size: 12px;}
A:link {text-decoration: none; color: blue}
A:visited {text-decoration: none; color: blue}
A:active {text-decoration: none; color: blue}
A:hover {text-decoration: underline; color: blue}

#images, #folders, #files { border: 1px solid #000000; background-color: #fff; margin: 50px; padding: 25px; }


DIV.image { width: <?php echo $THUMBNAIL_WIDTH; ?>; height: <?php echo $THUMBNAIL_HEIGHT; ?>; float: left; margin: 10px; text-align: center; border: 0px; }
IMG { border: 1px solid #444; background-color: #eee; }
</style>
</head>
<body>

<p><br><p><table width=100%><tr width=100%><td width=100%><h2>Title</h2>
<font face=tahoma>

<?php

$Browse = $_GET["b"] ;

if ( $Browse )
{
	$Browse .= "/";
}

// Stop them accessing higher level folders
if ( substr_count( $Browse, ".." ) > 0 || substr_count( $Browse, $THUMBNAIL_FOLDER ) > 0  )
{
	echo "You don't have permission to access this folder!";
	exit();
}

$DIR = "./" . $Browse;
$d = dir( $DIR );

while (false !== ($entry = $d->read())) 
{
	if ($entry[0] == '.') continue;
	if ( in_array( $entry, $HIDDEN_FILES) ) continue;

	// Don't list the folder if it has an index!
	if ($entry == 'index.html') exit();
	if ($entry == 'index.htm') exit();
	if ($entry == 'index.php') exit();
	if ($entry == 'index.asp') exit();

    I just noticed something that can help to clarify. Using the sorting I have in my code, it actually is sorting... but the sorting is broken up into two groups. First it runs through the shorter names alphabetically, then it starts over at "A" and runs through the longer names alphabetically... why would it do this?

    Have you tried natcasesort() instead of arsort() ?

    Yea, I tried asort, sort, natsort, natcasesort, etc. Although I get a different result with the latter two, none of them give me an alphabetical sort. And actually, the latter two don't seem to sort them at all.

    Also, I shortened the name of one of the longer entries thinking that it would change position in the sort, since they seem to be grouping into two separate alphabetical groups (one for shorter entires and one for longer ones of 9+ characters), but it stayed in the same position. So it's not due to length.

    I really don't get this. I just want the array to sort in alphabetical order. But for some reason, it is separating some of them from the others and then, secondarily, sorting the two groups alphabetically...

    Well, I've pretty much narrowed down the problem. When I make some change to a file in the folder, that folder pops to the top of the list in its parent folder (where I have this php code displaying the contents of that folder). So it is actually sorting them by the date of the folder's contents. The partially alphabetical sorting is just due to the fact that they mostly uploaded in that order.

    ANY help on why it would be doing this would be appreciated...

    Well, I figured it out myself. The use of filemtime instead of basename in the array was the problem.
