id3_remove_tag

(PECL)

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 writable and contained a 1.0 tag, this will output: 

Tag succesfully removed

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.

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