Subject: Ruby's a = b vs PHP5's $obj1 =& $obj2

Just want to confirm Ruby's

  a = b

is the same as PHP5's

  $obj1 = $obj2

in other words, the reference is copied.

While

  $obj1 =& $obj2

or

  $obj1 = &$obj2

in both PHP4 and PHP5 isn't the same as Ruby's   a = b

$obj1 and $obj2 just become synonyms...

and after

$obj1 = new Foo("foo1");
$obj2 =& $obj1
$obj2 = new Foo("bar1");

$obj1 and $obj2 have the same content, as they are just synonyms. (not a
clone, not same reference, but just synonyms).  The "foo1" object is
garbage-collected since no one is referencing it.

this is giving me an initial headache... until maybe after i get used to
it.
