(PECL id3:0.1-0.2)
id3_get_tag — Get all information stored in an ID3 tag
说明
id3_get_tag() is used to get all information stored in the id3 tag of the specified file.
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
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.
返回值
Returns an associative array with various keys like: title, artist, ..
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.
