#29702 [NEW]: $a=$GLOBALS works as $a=&$GLOBALS

[andrea dot busia at axis-sv dot it]

From:             andrea dot busia at axis-sv dot it
Operating system: Win / Linux
PHP version:      5.0.1
PHP Bug Type:     Scripting Engine problem
Bug description:  $a=$GLOBALS works as $a=&$GLOBALS

Description:
------------
In this script seems that the $GLOBALS value is changed by the unset
statement but I want to modify $ar, $GLOBALS must remain the same as
before.


Reproduce code:
---------------
<?
$xml=array("aaa", "bbb", "ccc");
foo();

function foo() {
        var_dump($GLOBALS["xml"]);
        $ar=$GLOBALS;
        unset($ar['xml']);
        var_dump($GLOBALS["xml"]);
}
?>

Expected result:
----------------
array(3) {
  [0]=>
  string(3) "aaa"
  [1]=>
  string(3) "bbb"
  [2]=>
  string(3) "ccc"
}
array(3) {
  [0]=>
  string(3) "aaa"
  [1]=>
  string(3) "bbb"
  [2]=>
  string(3) "ccc"
}


Actual result:
--------------
array(3) {
  [0]=>
  string(3) "aaa"
  [1]=>
  string(3) "bbb"
  [2]=>
  string(3) "ccc"
}
NULL
