How to get meta data out of mp3 files

问题

Can anyone recommend a good standalone class (not part of PEAR) or another method for me to grab some basic meta data from about 1,400 MP3 files?

Works with both ID3 v1 and V2. Reads more than just id3 but should fit the bill. You can also play with the following taken from http://www.htmlhelpcentral.com/messageboard/showthread.php?t=12006

<? 
class CMP3File { 
 var $title;var $artist;var $album;var $year;var $comment;var $genre; 
 function getid3 ($file) { 
  if (file_exists($file)) { 
   $id_start=filesize($file)-128; 
   $fp=fopen($file,"r"); 
   fseek($fp,$id_start); 
   $tag=fread($fp,3); 
   if ($tag == "TAG") { 
    $this->title=fread($fp,30); 
    $this->artist=fread($fp,30); 
    $this->album=fread($fp,30); 
    $this->year=fread($fp,4); 
    $this->comment=fread($fp,30); 
    $this->genre=fread($fp,1); 
    fclose($fp); 
    return true; 
   } else { 
    fclose($fp); 
    return false; 
   } 
  } else { return false; } 
 } 
} 
?>
