Hi,I have an offline xspf playlist generator I found on the web that works well offline.Now I want to be able to call or execute the vbs file with my mp3 files on the server in order for the playlist.xml file to be updated everytime the page is visited. This way, all i need to do is to upload my mp3 on the server and my mp3player will have updated list everytime the page loads (i guess there is a tricky part there. xml needs to be updated before my mp3player start loading otherwise it will load the playlist before it is updated)Here is the code of the vbs file

it works by simply dragging the folder over that file (xspf_playlist_generator.vbs) and it will output a playlist in xspf format.Here is the playlist output format

<?xml version="1.0" encoding="UTF-8"?><playlist version="1" xmlns="http://xspf.org/ns/0/"><title>TITLE</title><info>http://www.yoursite.com/</info><trackList>	<track>			<title>title</title>			<location>some_music.mp3</location>	</track>	<track>			<title>title</title>			<location>some_music.mp3</location>	</track>	<track>			<title>title</title>			<location>some_music.mp3</location>	</track>	<track>			<title>title</title>			<location>some_music.mp3</location>	</track>	<track>			<title>title</title>			<location>some_music.mp3</location>	</track>	<track>			<title>title</title>			<location>some_music.mp3</location>	</track></trackList></playlist>

Anyone knows how can I use this xspf generator online?Thanks

I'm not sure what this has to do with PHP, but you can't use that generator online, it reads a local file structure. If you want to read a remote file structure you'll probably need to write code that opens an FTP connection to the server, logs in, finds the directory, and lists the files. That's substantially different than what you've got, it's more of an entirely new script than changes to this script. The only thing they'll have in common is that they both write the same output.
