This is a PHP library for reading information from a variety of chip music file formats. It also handles tag management.
To utilize this amazing fiasco ---
<?php
include('chiptag.php');
$chiptune = chiptag::open($chiptune_filename);
// chiptag guesses the format from the file's extension
// chiptag then creates an object from the appropriate class
$chiptune->FetchInfo(); // loads tags and other info
$chiptune->SetTag($tag_name,$value); // duh?
$chiptune->WriteTags(); // commit set tags to the file
echo $chiptune->ReadableReport(); // view history log
?>
Look inside the formats folder for info and examples on
adding more chiptune formats to this library.
