ID3 information is divided into two versions: v1 and v2. The ID3 of v1 is 128 bytes at the end of the mp3 file. it starts with a TAG and follows the song information. V2 is generally at the beginning of mp3 and can store large amounts of information such as lyrics, pictures of the album, and so on. -- [Baidu encyclopedia]

'; If (! Empty ($ tagwriter-> warnings) {echo 'There were some warnings:
'. Implode ('
