| Description: |
This piece of code takes in a directory as an argument, goes through the directory (but does not include subdirectories), and creates a HTML playlist, with a hyperlink for each entry. This hyperlink could be customized to be a link to a download, or in the case that I have used and tested, a link to a CGI script that queues a song in a playlist (useful for Shoutcast radio). The desired customization can be easily achieved by altering the $directory, $baselink, and $filename variables declared near the beginning of the script. |
