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 ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=54657&edit=1
