I've got a simple wrapper around SoX, a command line interface that writes a file at the specified output:
sox <input_filepath> <output_filepath>
I am trying to take a file uploaded by the user, give it the SoX treatment, then write it to storage by wrapping the above command in exec() or shell_exec.
However there is no output file.
Is this expected behaviour?
If yes, then how do I write a file using exec()?
Update: I'm 90% certain this is because of file permissions. The exact same command works when I run manually in the console, but not when executed by the server running locally.
Now I just need to figure out the best and safest way to change these permissions...
Any tips welcome!
SOLUTION:
This was not a permissions issue. I wasn't using the fully qualified filepath to my Sox installation.
If I install sox on a server, it's find to call sox <cmd>, but to a run a CLI tool in a local environment it needs to be C:/path/to/sox.exe sox <cmd>.
Hope this helps someone.
