## Example

`

     int id3_get_version ( string $filename )

`

## Description

id3_get_version() retrieves the version(s) of the ID3 tag(s) in the MP3 file. If a file contains an ID3 v1.1 tag, it always contains a 1.0 tag, as version 1.1 is just an extension of 1.0.

## Return Values

Returns the version number of the ID3 tag of the file. As a tag can contain ID3 v1.x and v2.x tags, the return value of this function should be bitwise compared with the predefined constants ID3_V1_0, ID3_V1_1 and ID3_V2.
