I would say use glob, unless there is a particular reason you're using opendir. The glob function will automatically parse the directory in alphabetical order, and so I've reversed it in the example below to show you how it works to order.

php Code:

/* Directory with or without trailing slash as rtrim will remove it anyway. */
$szDir = './app/controllers/';

/* Glob acquires all the files for us with the extension specified (WMV). */
$aFiles = glob(rtrim($szDir, '/') . '/*.wmv');

/* Glob already outputs in alphabetical order, so reverse to show it's working. */
$aFiles = array_reverse($aFiles);

foreach ($aFiles as $szFile)
{
    /* Echo the radio buttons using the relevant data. */
    printf
    (
        '<input type="radio" name="trailer" value="%s" /><font color="white">%s</font><br />',
        pathinfo($szFile, PATHINFO_FILENAME), basename($szFile)
    );
}
