Summary: __call does not return by reference
Status: Bogus
Type: Bug
Package: Scripting Engine problem
Operating System: *
PHP Version: 5CVS-2005-03-09

New Comment:
With all due respect, "only variables should be assigned by reference" makes no
sense.
__call does not assign variables. It executes code for innaccessible methods,
and that code may wish to return a reference.
Not bogus; this functionality existed in PHP4 as __call()'s third parameter was
passed by reference.
Although this is in no way justification for the fix (as I have already
justified it) consider this: (pedantic error checking removed for simplicity)
<?
class Foo
{
private $world;
function &__call($method,$params)
{
if( substr(0,3,$method) == 'get' )
return $this->{substr($method,3)};
}
function &__get($property)
{
return $this->{'get'.$property}();
}
}
$hello = new Hello;
$hello->world[] = 'php maintainers always say NO';
?>
--which does not work. For those of us mere 'users' who need this, as a work
around try this:
<?
class Hello
{
. . . include definition from above . . .
function &getWorld()
{
return $this->world;
}
}
?>
--which DOES work, although that is not really the point!

Andi, is this the final call? :)
(documentation or engine change..that is the question)

well, then that info about __call and return by reference should go into the
manual, in the __call section.
right?

At the moment __call() relies on the internal signature which is return by copy
and the fact that the engine prevents from implementing return by reference
functions at c-level.

I've just tested with latest php 5 (php5-200503080930)
and the problem is not solved.
