PHP version: trunk-SVN-2011-05-04 (SVN)
Package: Scripting Engine problem
Bug Type: Bug
Bug description:Function parameters can no longer be named after superglobal
variables
Description:
------------
There is a backwards incompatible change in trunk in that function can no
longer have parameters with a name equal to the one of some superglobal.
This should either be fixed with the previous behavior (the parameter
shadows the superglobal) or documented in UPGRADING.
Test script:
---------------
$ php -d error_reporting=-1
<?php
function a($GLOBALS) {
$GLOBALS['h'] = 8;
}
$g = null;
a($g);
var_dump($h);
Expected result:
----------------
On 5.3:
Notice: Undefined variable: h in - on line 7
NULL
Actual result:
--------------
On trunk:
Fatal error: Cannot re-assign auto-global variable GLOBALS in - on line 2
