id3_get_version -- Get version of an ID3 tag


int id3_get_version ( string filename )

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.

Seznam parametrů


The path to the MP3 file

Instead of a filename you may also pass a valid stream resource

Návratové hodnoty

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.


Příklad 1. id3_get_version() example

= id3_get_version( "path/to/example.mp3" );
if (
$version & ID3_V1_0) {
"Contains a 1.x tag\n";
if (
$version & ID3_V1_1) {
"Contains a 1.1 tag\n";
if (
$version & ID3_V2) {
"Contains a 2.x tag\n";

Výše uvedený příklad vypíše něco jako:

Contains a 1.x tag
Contains a 1.1 tag
