PassThru() and the schemeinterpreter

Hi there,

I have a little problem. I'm trying to call a schemeinterpreter (chez scheme 'petite') with PassThru-function in PHP3.
It works, I can even see the Output on the browser but then I've tried to execute some commands f.e.: (load "file.ss") it seems to work (the return variable of the command is [0]) but I can't see output of this on the browser.
I've tried with system() and exec() but still nothing.
some code:

$cmd="/var/local/bin/petite";
passthru($cmd, $ret_var);
echo $ret_var;

Output:

Petite Chez Scheme Version 6.0a
Copyright <c> 1998 Cadence Research Systems>
0

and then:

$code="(define ... an so on)";
passthru($code, ret_var);
echo $ret_var;

as output comes only:

0

Maybe anyone of you knows what should I do?
PERL - advice wouldn't be bad too.

As far as I know, passthru() only accepts filepaths and URLs and all it does is suck the input in one end and spit it out the other...

Your example is a little vague- perhaps you could post something a little more substantial and I could tell you what to use in place of passthru... if you're trying to execute PHP code from a string, try eval().
