WML/PHP Listing files

Hi,
I've got a wap/http website that offers free games, appz, ringtones and images to download. (tsm100.iespana.es)

I've got this script in php and would like to implement it into a wml page, but i can't, i doesn't work. Can someone help me?

<?
$path="/melodias";
$directorio=dir($path);

echo "Directorio ".$path.":<br><br>";

while ($archivo = $directorio->read())
{
if ($archivo == "." OR $archivo==".." OR $archivo==".listfic" OR $archivo=="melodias.php") {
}else{
echo "<a href=".$archivo.">".$archivo."</a><br/>";
}
}
$directorio->close();
?>

The script is working on a normal php page but not in the wml, can someone implement it or help me?
