id3_remove_tag

Remove an existing ID3 tag (PECL)
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 808. 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
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.
