Maxima use with php -

-

i try use function shell_exec() or system() execute maxima scripts php. example:

<?php chdir("c:\program files (x86)\maxima-sbcl-5.35.1.2\bin"); $cmd = "maxima"; $res = exec($cmd,$out,$status); echo "out="; print_r($out); echo "res=".$res.php_eol; echo "status=".$status.php_eol;` ?>

output:

out=array (     [0] => maxima 5.35.1.2 http://maxima.sourceforge.net     [1] => using lisp sbcl 1.2.7     [2] => distributed under gnu public license. see file copying.     [3] => dedicated memory of william schelter.     [4] => function bug_report() provides bug reporting information.     [5] => (%i1) ) res=(%i1) status=0

in match "(%i1)_" have run script "solve(x^2-1=0, x)";

but it's not recognized cmd script.

you’re trying run maxima in interactive mode, i.e. start command shell , interactively enter expressions , results in return.

what need non-interactive mode. according maxima’s man page, there 2 ways work in non-interactive mode: --batch , --batch-string (also, --batch-lisp, that’s not relevant here).

the first method expects pass file name expressions processed. second method allows define string command line.

in example, should invoke maxima following:

$expr = escapeshellarg("solve(x^2-1=0, x)"); $cmd = "maxima --batch-string=$expr"; // … , on

if want more complex calculations, should dump them temporary file , pass file location maxima via --batch parameter.
