I still find it a bug. I need a reference to $this for BC with PHP4 in
the following piece of code:
function &getRootDataSource() {
$root =& $this;
while ($root->parent != NULL) {
$root =& $root->parent;
}
return $root;
}

Objects are already references in PHP 5, thuse there is no sense in
...&$this in any way.

Description:
------------
PHP 5.1RC1 throws fatal error when some variable gets assigned with
$this by reference. However there's a workaround for this fatal error
which is very simple: using a helper function which simply returns the
passed argument by reference. I'm a bit lost here - what is the
expected behavior?
Yes, it may seem a bit weird to assign objects by reference in PHP5 but
if you keep your code base PHP4 compatible you know what i mean.
Reproduce code:
---------------
<?php
function & getRef(&$ref) {
return $ref;
}
class Foo {
function Foo() {
//$ref =& getRef($this); //works just fine
$ref =& $this; //throws "cannot re-assign $this" fatal
$ref->test();
}
function test() {
echo 'test';
}
}
$foo = new Foo();
?>
Expected result:
----------------
test
Actual result:
--------------
Fatal error: Cannot re-assign $this
