ain't that the other way around ?
$var1=$var2 ($var1 is a copy of $var2)
$var1=& $var2 ($var1 is a reference to $var2)
$var1='Test'
echo $var2 (outputs Test)

REFERENCES.
the object you get back is a copy (foreach has the same
effect as creating a new variable as in the example below).
... see below ...
notice the use of the & symbol (and the 'refcount' values).
(there is loads of info out there on references/php4/objects
out there that explain it better than me.) - see what happens
when you start removing '&'s.
or you could try php5 and forget about 'object hell'. :-)

The function that gives me trouble

foreach($this->subposter AS $konto){
$konto->fyll_fra_post($pv);

class Test
{
var $number;
var $subposter;
function Test($n = 0) { $this->number = $n; }
function sqar() { if (is_numeric($this->number)) { $this->number *=
$this->number; } return $this; }
function doit() { echo strval($this->number),"\n"; }
function make() {
static $c = 1;
$t = new Test($c++);
$s =& $t; // watch what happens when you remove the '&' (php4 only)

$this->subposter[] = $t->sqar();
}
function goan() {
$cnt = count($this->subposter);
$this->doit();
for($i=0;$i<$cnt;$i++) {
// watch what happens when you remove the '&' (php4 only)
$tmp =& $this->subposter[$i];
$tmp->sqar();
$this->subposter[$i]->doit();
}
}
}
$t = new Test("infinity"); $i = 0;
while($i++ < 5) $t->make();
$t->goan();
}
-------------
$this->subposter is the array of CLASS2
function fyll_fra_post($post_vars){
echo "(gruppe)class = ".get_class($this) ."<br>\n";
$teller=0;
foreach($this->poster AS $post=>$verd){
$best="bestilt_".$post;
$avik="avvik_".$post;
$fakt="faktura_".$post;
$this->poster[$post]["bestilt"]=$post_vars[$best];
$this->poster[$post]["avvik"]=$post_vars[$avik];
$this->poster[$post]["faktura"]=$post_vars[$fakt];
}
$this->endret='ja';
$this->sett_sum();
}
If I print the data (after setting the new data) inside
'fyll_fra_post' it puts out the new data.
If I do the same from 'fyll_sub_konto' (after foreach) it gives me
the old data.
