id3_remove_tag -- Remove an existing ID3 tag
Description
bool 
id3_remove_tag ( string filename [, int version])
     id3_remove_tag() is used to remove the information stored
     of an ID3 tag. If no tag has been present, it will return FALSE and leave the file
     as it was.
    
注: Instead of a filename you may also pass a valid stream resource.
     The optional version parameter allows you to
     specify the version of the tag as MP3 files may contain both, version 1.x and
     version 2.x tags.
    
     
| 例子 1. id3_remove_tag() example | 
<?php$result = id3_remove_tag( "path/to/example.mp3", ID3_V1_0 );
 if ($result === true) {
 echo "Tag succesfully removed\n";
 }
 ?>

       If the file is writeable and contained a 1.0 tag, this will output:
       | 
    注: 
      Currently id3_remove_tag() only supports
      version 1.0 and 1.1. If you choose to remove a 1.0 tag and the file
      contains a 1.1 tag, this tag will be removed, as v1.1 is only an
      extension of 1.0.
