Nearly there :)

I get a this in the beginning:
PHP Warning: PHP Startup: mm_create(0,
/var/lib/php5/session_mm_cli1000) failed, err mm:core:
failed to open semaphore file (Permission denied) in Unknown on line 0

It starts its job though and seems to do it except that it can't handle
apostrophes in filenames:

sox FAIL formats: can't open input file `The': No such file or directory

sh: -c: line 0: syntax error near unexpected token `)'
sox FAIL formats: can't open input file `The': No such file or directory

Those are with files like Let's Fall In Love.ogg
Stormy Weather (Keeps Rainin' All The Time).ogg
Trav'lin' Light.ogg

Such files are left untouched.

Delete the above two lines, and replace them with:

if($files===FALSE) // none found
continue; // skip to next directory

>> passthru("sox '".$file."' '".$output."'",$ret_val);

and replace the above line with:

passthru("sox ".escapeshellarg($file)." ".escapeshellarg($output),$ret_val);


which escapes the variables so they can safely be passed to the shell.

Interesting. Don't know why it would be wanting to open a semaphore
file.

Oops. Fix for that is above.

Although `ls *.jpg` gives a slightly different result than the mentioned
`find` command of course... :) But the meaning is clear.

And indeed `find` is not just better for cosmetic reasons (yeah I know,
matter of taste), but also prevents cmd-line buffers to overflow when a
lot of files exist.
