Alphabetize files from a folder in a select box

[JoeAtRevolutionUnltd]

Is it possible to alphabetize files from a folder in a select box? I was told it is possible with just HTML but after a few hours of searching i'm coming up empty.

Maybe a little PHP might help...

<?php
//deinf the array
$filelist = array();

//check to see if the folder exists
if ($handle = opendir('/usr/bin')) {
	$i=0;
//loop through the folder and store in the array
	while (false !== ($file = readdir($handle))) {
		$filelist[$i] = $file;
		$i++;
	}
	closedir($handle);
}

//sort the array alphabetically
asort($filelist);

//create the select box
echo "<select multiple=yes size=10>";

//loop through the array and add the options
	foreach ($filelist as $k=>$v){
	echo "<option value='$k'>$v</option>";
	}
echo "</select>";
?>

I meant

//define the array

i would not rely on the the numeric key as the identifier or the option items. there is a chance that the directory might change in the meantime.

i'd also add some validation to mark's script

while (false !== ($file = readdir($handle))) {
        if (is_file($file)){
          $filelist[] = $file;
        }
}

if you do want directories as well, then check instead for the dot and doubledot. but you'd be better off using glob() in that case. or even ls via the backticks.
