# id3_get_version

(PECL id3:0.1-0.2)

id3_get_version — Get version of an ID3 tag

### Description

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.

### Parameters

`filename`

  The path to the MP3 file

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

### 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`.

### Examples

Example#1 id3_get_version() example

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

The above example will output something similar to:

    Contains a 1.x tag
    Contains a 1.1 tag
