id3_remove

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.
