from php class

[tims-corbett]

Hi,

I am running a vagrant box.

the following works fine: nohup octave-daemon -d -c /etc/octave-daemon.conf&

from the quick start examples, the following works great in /var/www/html/test.php without even starting the daemon: require "Octave_lib.php"; $octave=new Octave(false); echo "Result=".$octave->query("1+2");

however, the following fails: $octave=new Octave("127.0.0.1);

the same code fails when placed in a php class (symfony Controller). says Command did not run successfully on line "new Octave"

what are the fixes?

The first issue is easy to fix – just replace the path in the script with whatever works for you. I didn't have the time and curiosity to make the init scripts truly portable. If you can find a way to make it work on most (all?) distros, by all means, do send in a patch.

Regarding the second issue, please include the error specifically. As it stands, you have an obvious syntax error in that line (you never close the hostname string), but I'm not sure that's exactly the code you're trying to run.

Thanks for the response. Closing the string was only a typo here

require "absolute.path/Octave_lib.php"; $octave=new Octave("127.0.0.1"); echo "Result=".$octave->query("1+2");

Yields "Result=" Instead of "Result=3"

However new Octave (false) works perfect above.

Issue 2: require "absolute.path/Octave_lib.php"; class DefaultController extends Controller { /* * @Route("/", name="homepage") / public function indexAction(Request $request) { $octave=new Octave(false); }

results in "139 command did not run successfully

Issue 1: did you successfully start the daemon before running that?

Issue 2: that looks like something idiosyncratic to your particular setup within that framework, and you should probably try to simplify the use case to a less esoteric class instead of Octave (perhaps a simple, home-brewed example).

Issue 1 nohup octave-daemon -d -c /etc/octave-daemon.conf&

Seemed to have worked fine. How can I check it?

Issue 2 I would like to use the php symfony framework ( model view controller architecture) Utmost I can try moving the octave call to model file and try again

Issue 1: don't nohup it – run it in a separate console and see what it does

Issue 2: I get that; I was suggesting a way to experiment with Symphony replacing the Octave class with a simpler class temporarily; maybe it's an issue with includes, or whatever else.

Issue 2: SOLVED There is some suggestion here: http://stackoverflow.com/questions/38237651/octave-daemon-from-php-class-file/38251500#38251500

Worked after copying "classes" folder and saying "use Octave"
