#27193 [NEW]: the visibility of class constructor cannot be changed

From: andrey@php.net Operating system: linux PHP version: 5CVS-2004-02-09 (dev) PHP Bug Type: Zend Engine 2 problem Bug description: the visibility of class constructor cannot be changed Description: ------------ While it's no problem to change the visibility of a constructor (limit the visibility) when using the old way of declaring a constructor (function with the same name as the class), it's not possible to lower the visibility in a hierarchy where the constructors are named after the new standard : __construct() . The engine have to check whether the name is __construct() (what about __destruct()? ), and not to complain in this case that the visibility is lowered. The first example emits a fatal error. The second is perfectly valid. Reproduce code: --------------- php -r 'class a{public function __construct() {}} class b extends a {private function __construct(){}}' php -r 'class a{public function a() {}} class b extends a {private function b(){}}' Actual result: -------------- PHP Fatal error: Access level to b::__construct() must be public (as in class a) in Command line code on line 1 -- Edit bug report at http://bugs.php.net/?id=27193&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=27193&r=trysnapshot4 Try a CVS snapshot (php5): http://bugs.php.net/fix.php?id=27193&r=trysnapshot5 Fixed in CVS: http://bugs.php.net/fix.php?id=27193&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=27193&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=27193&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=27193&r=needscript Try newer version: http://bugs.php.net/fix.php?id=27193&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=27193&r=support Expected behavior: http://bugs.php.net/fix.php?id=27193&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=27193&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=27193&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=27193&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=27193&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=27193&r=dst IIS Stability: http://bugs.php.net/fix.php?id=27193&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=27193&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=27193&r=float
