All you need to do is use some regular expressions in the PHP which check to 
make sure that the incoming variables conform to your expectations.

e.g. to make sure $num is a numeric value, strip all characters except 0-9, 
"." and "-".

$num = preg_replace("/[^0-9\.-]/", "", $num);

I guess you could call your octave program from the command line and pass 
args, or invoke the octave interpreter with popen().
