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