Actually what i have is quite similar to what you suggest. But it still
doesn't solve my double slash problem, where the value should be NULL.

The thingy i have to check if a filename is specified is the following:

if( preg_match( '/(\.html)$/', $loc[3] ) ){
$song_url = preg_replace( '/(\.html)$/', '', $loc[3] );
$song_extension = TRUE;
}else{
$song_extension = FALSE;
};

It checks all values in the array are UrlSafe(), wich means that they
are A-z, 0-9, -, _ That's also why i delete the last '.html', because
else validation would return false.
