Вместо того, чтобы просто делиться кодом для обновления обложек альбомов, я собираюсь опубликовать здесь весь свой класс-оболочку MP3 getID3, чтобы вы могли использовать его по своему желанию
Использование
$mp3 = new Whisppa\Music\MP3($mp3_filepath);
//Get data
$mp3->title
$mp3->artist
$mp3->album
$mp3->genre
//set properties
$mp3->year = '2014';
//change album art
$mp3->set_art(file_get_contents($pathtoimage), 'image/jpeg', 'New Caption');//sets front album art
//save new details
$mp3->save();

Примечание
Пока нет кода обработки ошибок. В настоящее время я просто полагаюсь на исключения, когда пытаюсь выполнить какие-либо операции.
Не стесняйтесь изменять и использовать по мере необходимости. Требуется PHP GETID3
