How does PHP cut audio files by time?

How does PHP cut audio files by time? My website needs to process user-uploaded audio files (in pcm or wav format) cyclically every 60 s.
Using PHP in the background of the website, how does one cut user-uploaded audio files by 60 s?

Can I explain in detail how to implement ffmpeg? Thank you!

Thank you! It seems that you still need to know the total duration of the audio file to determine when to end cutting. how can I write this command?

Thanks to the moderator, but I didn't find the command T for obtaining the audio duration.

(Video bit rate + audio bit rate) * Duration/8 = file size K
I don't know about the anti-calculation.

Thanks to the moderator. it seems that the article only describes how to set, adjust the bit rate, and file size, but does not explain how to view the original bit rate and size of the file ..
