First thing I would want to know is what is in SCRIPT_PATH? When you
say you execute it from your php script - do you mean running under the
web server? If so, does the web server have access to the script and
permission to execute it? The web server will almost always have
different permissions than the CLI user.

Are you sure the script is actually not executing, or could it be
executing but not producing any output?
