id3_get_tag

(PECL)

id3_get_tag -- Get all information stored in an ID3 tag

Description

array id3_get_tag ( string filename [, int version] )

id3_get_tag() is used to get all information stored in the id3 tag of the specified file.

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_get_tag() example

<?php
$tag = id3_get_tag( "path/to/example.mp3" );
print_r($tag);
?>

This will output something like: 

Array
(
    [title] => DN-38416
    [artist] => Re:\Legion
    [album] => Reflections
    [year] => 2004
    [genre] => 19
)

The key genre will contain an integer between 0 and 147. You may use id3_get_genre_name() to convert it to a human readable string.

Since version 0.2 id3_get_tag() also supports ID3 tags of version 2.2, 2.3 and 2.4. To extract information from these tags, pass one of the constants ID3_V2_2, ID3_V2_3 or ID3_V2_4 as the second parameter.

例子 2. id3_get_tag() example

<?php
$tag = id3_get_tag( "path/to/example2.mp3", ID3_V2_3 );
print_r($tag);
?>

This will output something like: 

Array
(
    [copyright] => Dirty Mac
    [originalArtist] => Dirty Mac
    [composer] => Marcus Götze
    [artist] => Dirty Mac
    [title] => Little Big Man
    [album] => Demo-Tape
    [track] => 5/12
    [genre] => (17)Rock
    [year] => 2001
)

ID3 v2.x tags can contain a lot more information about the MP3 file than ID3 v1.x tags.

See also id3_set_tag(), id3_remove_tag() and id3_get_version().
