PHP: How to convert from .caf to .mp3 format?

Question

I wonder if there is any way to convert the caf files to mp3 files using any api or any other methods for my web application built on php. I don't know this is possible in php or not.

I know i can use pacpl input.caf -to mp3 on my server to make it work but i have shared hosting and i would like to know if there is a way to do it.

Answer 1

If pacpl input.caf -to mp3 works at bash, why not call it from PHP like so:

shell_exec("pacpl input.caf -to mp3");

You may or may not need to reconfigure the permissions or use sudo in there depending on the host server config.
