id3_set_tag -- Update information stored in an ID3 tag


bool id3_set_tag ( string filename, array tag [, int version] )

id3_set_tag() is used to change the information stored of an ID3 tag. If no tag has been present, it will be added to the file.

Note: Instead of a filename you may also pass a valid stream resource.

The optional version parameter allows you to specify the version of the tag as MP3 files may contain both, version 1.x and version 2.x tags.

Example 1. id3_set_tag() example

= array(
"title" => "Re:Start",
"artist" => "Re:\Legion",
"comment" => "A nice track"
$result = id3_set_tag( "path/to/example.mp3", $data, ID3_V1_0 );
if (
$result === true) {
"Tag succesfully updated\n";

If the file is writable, this will output:

Tag succesfully updated

Note: Currently id3_set_tag() only supports version 1.0 and 1.1.

The following keys may be used in the associative array:
