Re: Re: CLASS/Object lifetime - > more info

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) roger Jochem Maas wrote:

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'. :-) roger helgesen wrote:

    }

} } $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.
