Hi
I use PHP 5.4.6-1ubuntu1.3 on my dev computer and PHP
5.3.3-7+squeeze17 on production server.
In php doc : http://www.php.net/manual/en/language.oop5.references.php
and http://php.net/manual/en/language.oop5.cloning.php
One of the key-points of PHP 5 OOP that is often mentioned is that
"objects are passed by references by default".
When an object is cloned, PHP 5 will perform a shallow copy of all of
the object's properties. Any properties that are references to other
variables, will remain references.
this->lines is an array of object created by "=" operator, it's a reference.
(See exemple 1 in cloning manual page)

Also, do you have an idea why this fails (copy by value) for property
this->lines and not all other ?

Which version of PHP do you use ?

Hi,
When i clone invoice with object in
htdocs/compta/facture/class/facture.class.php the invoice
lines aren't cloned.
The clone lines are referenced from origin invoice.
Add this function to class Facture (~ line 129) :
function __clone()
{
// Force a copy of this->lines, otherwise it will
point to same object.
for($i=0; $i < count($this->lines); $i++){
$this->lines[$i] = clone $this->lines[$i];
}
}
In french :
Lorsque l'on clone une facture via la classe facture dans
compta (fichier
htdocs/compta/facture/class/facture.class.php), les lignes de
la facture ne sont pas clonés mais simplement copiées par
référence.
Il suffit d'ajouter la fonction pour cloner les lignes et cela
fonctionne !
Probléme constaté sur la version 3.3.1 et a l'air d'être
toujours présent dans la version 3.4.0
Cordialement,
Sébastien
