return object instance

How do you return an object from a function? Take the following
snippet...

class Stuff
{
public $nNum;
public $szText;
}

function MakeStuff
{
$oObject = new Stuff;

$oObject->nNum = 123;
$oObject->szText = "Hello";

return $oObject;
}

function EntryPoint
{
$oStuff = MakeStuff(); // oStuff will equal NULL
}

I've tried all sorts but i just can't get an object passed out of a
function. Its mainly useful for returning a collection of errors and
the like. But how do you do it in php5?

If anyone could help i would be eternally grateful.

You need to write your function definitions like this:

function MakeStuff() {

}
function EntryPoint() {

}

Note the parentheses.

<?php
class Stuff {
public $nNum;
public $szText;
}

function MakeStuff() {
$oObject = new Stuff;
$oObject->nNum = 123;
$oObject->szText = "Hello";
return $oObject;
}

function EntryPoint() {
$oStuff = MakeStuff(); // oStuff will equal NULL
var_dump($oStuf f);
}

EntryPoint();
?>

output:

object(Stuff)#1 (2) {
["nNum"]=>
int(123)
["szText"]=>
string(5) "Hello"
}

Oops, i do usually have the parenthasis, somehow forgot to add them
whilst composing the example.

Also, this code seems to work when i expected it not to. Must be
something else about my site that's messing up.

Sorry about that. I always make comedy mistakes when starting out
with a new language.

OK, it appears to be a problem with the debugger.
I'm using http://dd.cron.ru/dbg/ together with PHPEclipse.

var_dump displays the correct contents, as does echoing individual
vars. BUT, the debugger shows the returned object to be NULL.

Hi, I have a set of simple webservices calls that worked fine using .NET Framework 1.0. I am calling a Java/Apache based webservices, the calling side is not able to supply a proper WSDL. What it does is to call a webservice with two parameters, one being a integer, the other one being a "String" which contains XML (not the best practice, however that is the target interface and we cannot change that).
