When you run it from the shell, you are you.
When you run it from a PHP web-server, you are not you. You are
whatever user is configured in httpd.conf
That user will not have the same rights/permissions as you do.
They also won't have your same environment, e.g., home directory $HOME.
Check permissions on all files/directories.
Use complete pathnames from the root hard drive:
/home/apple/path/to/$outputFile
