[phpsoa] problem with require_once and global
Hi everybody,
to be clear i will explain my problem using the code below.
My problem is: when i use "m1" i obtain this error:
[Wed Mar 14 01:20:37 2007] [error] PHP Notice: Fatal: CFG is not
configured! Exiting. in /home/messe318/setup.php on line 93
/home/messe318/setup.php(93) : Notice - Fatal: CFG is not configured!
Exiting.
why "global $CFG" doesn't wok into setup.php using SCA (if i call
setup.php directly it work) ?
the problem is i can't change config.php and setup.php, i can chage
pluto.php and pippo.php.
thank you in advance.
mbertazz
pluto->m2($a,$b);
}
}
?>
k= '123';
$CFG->z= '456';
require_once("setup.php");
?>
k)) {
trigger_error('Fatal: CFG is not configured! Exiting.');
die;
}
function m3()
...
?>

[phpsoa] passing parameters by reference
Hi all, i've a question about passing parameters by reference and not by value. I'm using WS binding to talk with a remote service. I can't change or ask to change that remote service and it use a "by reference" approach. Is there some way to use SCA impl. in this particular case? I think it's not a useful way to force access to private attribute of returned object... I read this sentence in SCA documentation: "How parameters are always passed by value (and not by reference) between components, even when the calls are local. This ensures that the semantics of a call do not change depending on the location of a component." I can agree, but can you explain me deeply WHY "passing by reference" is not supported so i can be more "strong" defending it?

[phpsoa] Re: passing parameters by reference
Dear Graham, thank yuo for your answer. I'm attaching the wsdl file. As you can see there are "in/out" paramenters. When i make a call i can't access the result because it's private.
