Bug #54657 [NEW]: Function parameters can no longer be named after superglobal variables

From: cataphract Operating system: Any 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 -- Edit bug report at http://bugs.php.net/bug.php?id=54657&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=54657&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=54657&r=trysnapshot53 Try a snapshot (trunk): http://bugs.php.net/fix.php?id=54657&r=trysnapshottrunk Fixed in SVN: http://bugs.php.net/fix.php?id=54657&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=54657&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=54657&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=54657&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=54657&r=needscript Try newer version: http://bugs.php.net/fix.php?id=54657&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=54657&r=support Expected behavior: http://bugs.php.net/fix.php?id=54657&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=54657&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=54657&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=54657&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=54657&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=54657&r=dst IIS Stability: http://bugs.php.net/fix.php?id=54657&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=54657&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=54657&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=54657&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=54657&r=mysqlcfg
