Try using a 
#! /usr/bin/octave -q 
as the first line of your script grph.m & make it
chmod +x, and run it.

For Bash scripts,
you can set GNU Plot's preferences to plot to the
GUI terminal or to a eps/png/jpeg file. See `info
octave/plotting`.

As for php scripts,
try an execve() on octave! 

Rather, run your script 'grph.m' from the terminal
and as said above set the term of gnuplot to a png
file. Later from PHP you can access this file.

IMHO this must work.
