How does PHP cut audio files based on time period?

I am writing a website that requires a user-uploaded audio file (in the form of PCM or WAV) to be cycled per 60s
In the background of the Web site PHP, how to upload the user audio files in accordance with 60s to cut?

Thank you Moderator! It seems to be necessary to know the total length of the audio file, so as to determine when to end the cutting bar, how to write this command?

Thank you moderator, but I did not find the command in the audio time length can be obtained T T

(Video bitrate + audio bitrate) * Duration/8 = file size K
I don't know.

(Video bitrate + audio bitrate) * Duration/8 = file size K
I don't know.

Thank you moderator, as if the article only said how to set, adjust the bitrate, file size, and did not explain how to view the original code rate and size of the file.
