(PECL id3 >= 0.1)

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.
