id3_set

Description

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.

注意: 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.

例 1. id3_set_tag() example
<?php $data = 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) { echo "Tag succesfully updated\n"; } ?>
If the file is writeable, this will output:
Tag succesfully updated

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