PHP 5.0 passes objects by reference automatically?

[lawrence]

Do I understand correctly that in PHP 5.0 objects will be passed by
reference (by handle, they say) automatically, not as a copy, as
happens with most PHP variables?

That's right.
It will be like in Java - variables are just references (or like Zend
call them: handles) to objects.
This will be a big performance improvement!

It is not a real performance improvement. You could always do that in
PHP 4, except that you needed to use the & operator to avoid copying
like this:

$my_object = &new my_class;

5 ... (apache2+php5b1 )

Unless I am missing something in this code snippet, there isn't any
language that would ever print back 7 since the method Foo is never
invoked. This isn't a property of the language, instead its the
behaviour of you code.

I haven't had time to test PHP5, so could someone test this code:
class Test
{
public $i;
function __construct($i)
{
$this->i=$i;
}
}

function foo($obj)
{
$obj=new Test(7);
}

$obj=new Test(5);
echo $obj->i;

is it like java where it would print 5? or does PHP5 is smarter and
prints 7?
