#45334 [NEW]: Method hiding/visibility issue

From: kristianoye at gmail dot com Operating system: Windows XP PHP version: 5.2.6 PHP Bug Type: Class/Object related Bug description: Method hiding/visibility issue Description: ------------ This issue was brought up in Bug #42830 but the bug was closed as 'Bogus' but to me it seems to be a valid issue: I am working on a small framework of my own and all objects share a common ancestor (base object) that defines __construct as public. I cannot redefine the visibility of __construct in the base without breaking other classes, yet I still want this derived, singleton to share the relation. Addendum: This seems to be the case with any method, actually, not specific to __construct(). I tried defining a 'GetMessage()' method in the same class structure. Reproduce code: --------------- class BaseObject { public function GetMessage() { return "foo1"; } } class RequestObject extends BaseObject { public function GetMessage() { return "foo2"; } } class CurrentRequest extends RequestObject { private function GetMessage() { return "top secret"; } } Expected result: ---------------- No errors for restricting visibility of methods in derived classes (I can understand not letting you *increase* visibility of derived methods, but not the other way around). Actual result: -------------- PHP Fatal error: Access level to CurrentRequest::GetMessage() must be public (as in class RequestObject) in C:\kristian\workspace\guild\foo.php on line 15 -- Edit bug report at http://bugs.php.net/?id=45334&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=45334&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=45334&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=45334&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=45334&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=45334&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=45334&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=45334&r=needscript Try newer version: http://bugs.php.net/fix.php?id=45334&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=45334&r=support Expected behavior: http://bugs.php.net/fix.php?id=45334&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=45334&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=45334&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=45334&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=45334&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=45334&r=dst IIS Stability: http://bugs.php.net/fix.php?id=45334&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=45334&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=45334&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=45334&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=45334&r=mysqlcfg
