(no version information, might be only in CVS)
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. 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.
Note: Instead of a filename you may also pass a valid stream resource.
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";
}
?>
|
This will output something like:
Contains a 1.x tag
Contains a 1.1 tag |
|
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.
