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
