[phpsoa] Re: problem with require_once and global
Hi mbertazz,
This is a tricky little problem. The essence of the problem is that
config.php only expects to find itself called from the very top level
script, where all variables are global. That is why it does not bother
to do global $CFG itself. However, when we call pippo.php for the
first time e.g. from a client script like:
?php
/* client.php */
include_once('SCA/SCA.php');
$s = SCA::getService('pippo.php');
echo $s-m1('a','b');
?
then the require_once(config.php) is being called from a script that
is already several calls down from in the call stack.
The following fix works for calling the component locally:
?php
/* client.php */
require_once('config.php');
include_once('SCA/SCA.php');
$s = SCA::getService('pippo.php');
echo $s-m1('a','b');
?
whihc gets the call to config.php done nice and early.
I haven't checked what will happen when we use the pippo.php as the
target of a webservice call, when it will be being called at the top
level again. I will try that tomorrow.
Hope that helps,
Matthew

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.

hi Matthew,
thank you very much for your help.
I haven't checked what will happen when we use the pippo.php as the
target of a webservice call, when it will be being called at the top
level again. I will try that tomorrow.
yes, this is the real problem i found: i'm calling it as the target of
a webservice call.
thank you again,
