Is it possible to inject IDv3 into MP3 stream?

I'd making a relay audio stream server (like shoutcast relaying but with customization) in PHP. Is it possible to dynamicly add IDv3 tag's every specified pack of dat开发者_StackOverflow中文版a (maybe every second - every 64KB)? If it`s possible how to do it?

IDv3 tags occur at the beginning of a mp3 but as an mp3 is just a series of frames due to the way it's possible to cut them with say mp3splt without re-encoding that stream would be IDv3 tags followed by mp3 data and then it would repeat in the same format for the next part of the stream

clearly i'm ignoring a lot of the details
