My friend Ray was uploading some musics of his to his private network so he can listen to them anywhere he wants without sharing them. So I build wrote this simple PHP page for him to let him build a simple music player by just clicking: (Note: XSPF is the standard for MP3 playlists Details at http://www.xspf.org/)

include 'SecurityChecking.php';
$FileList=filesInDir('SOMEDIRECTORY');
$content="\n".
	 "\n".
	 "\n";
foreach($FileList as $file)
	$content.=""SOMEDIRECTORY.$file."\n"; //And other mp3 meta infos.
$content.="\n\n";
$file="default.xspf";
$fh = fopen($file, 'w+') or die("can't open file");
fwrite($fh, $content);
fclose($fh);
echo "Successful! Thanks to Edison.";
function filesInDir($tdir){
	$dirs = scandir($tdir);
        foreach($dirs as $file){
                if (($file == '.')||($file == '..')){}
                elseif (is_dir($tdir.'/'.$file))
                        filesInDir($tdir.'/'.$file);
                else
                        $return[]=$file;
        }
	return $return;
}
