id3_remove_tag — Remove an existing ID3 tag

说明

id3_remove_tag ( string $filename [, int $version = ID3_V1_0 ] ) : bool

id3_remove_tag() is used to remove the information stored of an ID3 tag.

参数

filename

The path to the MP3 file

Instead of a filename you may also pass a valid stream resource

version

Allows you to specify the version of the tag as MP3 files may contain both, version 1.x and version 2.x tags.

返回值

成功时返回 TRUE， 或者在失败时返回 FALSE。

范例

Example #1 id3_remove_tag() example

<?php
$result = id3_remove_tag( "path/to/example.mp3", ID3_V1_0 );
if ($result === true) {
    echo "Tag successfully removed\n";
}
?>

If the file is writable and contained a 1.0 tag, this will output: 

Tag successfully removed

注释

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.
