You first pull in the list of files, save it to an array, then sort that array before displaying.

Why does this not work? I added the code in the red.

/* open the directory */
$dirFiles = array();
$CURRENT_DIR = “$exec_root_dir”;
if ($MY_DIR) { $CURRENT_DIR = “$CURRENT_DIR/$MY_DIR”; }
$handle = @opendir($CURRENT_DIR) or die(“Unable to open this directory”);

/* loop through files in directory */
while (false!==($file = readdir($handle))) {

$dirFiles[] = $file;

    /* watch out for . and .. */
    if ($file != "." && $file != "..")

{

sort($dirFiles);
foreach($dirFiles as $file) 

            /* process as directory only if one level deep*/
            if (is_dir("$CURRENT_DIR/$file") && !$MY_DIR) {
                    print("
                            <form action='index.php' method='post'>
                                    <input type='hidden' name='MY_DIR' size='20' value='$file'>
                                    <input type='submit' value='$file' name='D-type' class='btn3' onmouseover='this.className=\\"btn3 btnhov\\"' onmouseout='this.className=\\"btn3\\"' />
                            </form>
                    ");
            }

            /* process as file */
            if (is_file("$CURRENT_DIR/$file") && is_executable("$CURRENT_DIR/$file") ) {
                    $fp = fopen("$CURRENT_DIR/$file",'r');
                    $filetext = fread($fp,filesize("$CURRENT_DIR/$file"));
                    fclose($fp);

                    /* do we want to display this file? */
                    if ( preg_match('/#\\$exec_allow=yes/',$filetext)  || $exec_allow_all) {
                            /* pull out output file */
                            if ( preg_match('/#\\$exec_out=(.*)/',$filetext,$matches) ) { $exec_out=$matches[1]; }

                            /* pull out description or use filename */
                            if ( preg_match('/#\\$exec_name=(.*)/',$filetext,$matches) ) { $exec_name=$matches[1]; }
                            else { $exec_name=$file; }

// print (“$exec_out<br>”);
print("

<input type=‘hidden’ name=‘MY_DIR’ size=‘900’ value=‘$MY_DIR’>

");
}
}
}
}

/* close the directory */
closedir($handle);
