Bug description: Fatal error: Cannot re-assign $this(again)
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
