# id3_remove_tag

(no version information, might be only in CVS)

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.

> 注意: 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 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:

    Tag succesfully removed

> 注意: 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.

See also id3_get_tag(), id3_set_tag() and id3_get_version().
