id3_remove_tag — Remove an existing ID3 tag
id3_remove_tag() is used to remove the information stored of an ID3 tag.
The path to the MP3 file
Instead of a filename you may also pass a valid stream resource
Allows you to specify the version of the tag as MP3 files may contain both, version 1.x and version 2.x tags.
如果成功则返回 TRUE，失败则返回 FALSE。
Example#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 writable and contained a 1.0 tag, this will output:
Tag succesfully removed
Note: 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.
